<h2 dir="ltr"> What Are Cas9 Enzymes?</h2>
 Cas9 is the catalytic core of the CRISPR/Cas9 editing system. Sourced from Streptococcus pyogenes (SpCas9) or Staphylococcus aureus (SaCas9), recombinant Cas9 proteins are expressed and purified to high purity for direct use in ribonucleoprotein (RNP) complexes &mdash; currently the most widely recommended format for mammalian cell editing due to rapid activity onset and minimised off-target effects compared to plasmid-based delivery. Genome-editing performance depends on the appropriate nuclease format. Choose the Cas9 enzyme that aligns with your editing strategy.

<h2 dir="ltr"> How to Choose a Cas9 Enzyme</h2>
 PAM Requirement Wild-type SpCas9 recognises any genomic locus flanked by an NGG protospacer adjacent motif (PAM), occurring roughly every 8&ndash;12 bp in mammalian genomes. SaCas9 requires NNGRRT, though engineered PAM variants (KKH, KRH, KRKH) expand targetable space. Off-Target Sensitivity High-fidelity Cas9 variants carry substitutions in the recognition lobe that reduce non-specific DNA contacts, lowering off-target cleavage while maintaining on-target activity comparable to wild-type SpCas9 &mdash; recommended for therapeutic cell engineering and base editing. Editing Mechanism Wild-type SpCas9 generates a blunt double-strand break repaired by NHEJ (indels for knockout) or HDR (precise insertions). Nickase (D10A) cuts only one strand for paired-nick HDR strategies with reduced off-target indels. dCas9 carries mutations in both nuclease domains, enabling CRISPRa/CRISPRi gene regulation without DNA cleavage. AAV Compatibility SaCas9, at approximately 1 kb smaller than SpCas9, fits a complete Cas9 + sgRNA expression cassette within the ~4.7 kb AAV packaging capacity &mdash; enabling single-vector in vivo delivery without split-vector complexity. Storage and Handling Recombinant Cas9 proteins are supplied for stability during shipping and short-term storage at &minus;20 &deg;C or &minus;80 &deg;C. Repeated freeze-thaw cycles reduce activity; aliquoting upon receipt is recommended.
<h2 dir="ltr"> Specifications Context</h2>
 An RNP is a pre-formed complex of recombinant Cas9 protein and sgRNA; once electroporated, it acts immediately and is degraded within hours, reducing off-target cleavage and avoiding immune stimulation associated with plasmid or mRNA delivery.&nbsp;Recombinant Cas9 in RNP format is validated across HEK293, HeLa, iPSCs, T cells, primary neurons, and hepatocytes, though electroporation parameters typically require cell-type-specific optimisation. Product offerings reflect MBP's catalogue as of mid-2026.

<h2>What are PCR Cleanup Kits?</h2>
&nbsp;
PCR cleanup kits remove residual PCR reaction components -- primers (&lt;100 bp), primer dimers, unincorporated dNTPs, DNA polymerase, buffer salts, and mineral oil - from PCR amplification products using silica-membrane spin columns and a bind-wash-elute protocol. The purified PCR amplicon (&gt;=100 bp) is recovered in 20-50 ul of water or elution buffer, free of inhibitors that would interfere with downstream steps, including Sanger sequencing, restriction enzyme digestion, ligation, NGS library preparation, and in vitro transcription. The procedure takes 5-10 minutes using a standard microcentrifuge with no organic solvents, precipitation, or centrifugation spins beyond the bind/wash/elute steps. Use a PCR cleanup kit immediately after PCR whenever the downstream application requires an inhibitor-free amplicon - primers and excess dNTPs left in the reaction will reduce sequencing quality, compete in ligation reactions, and inflate NGS background noise.

&nbsp;
<h2>How to Choose a PCR Cleanup Kit</h2>
&nbsp;
Binding Capacity
Standard PCR cleanup columns bind up to 5-25 ug of DNA, depending on the kit; 25 ug capacity (Thermo Fisher GeneJET) accommodates typical preparative PCR reactions. For high-yield PCR reactions producing &gt;25 ug of amplicon, split the reaction across two columns and pool the eluates, or use a higher-capacity kit format.
Fragment Size Range
Standard PCR cleanup kits retain fragments &gt;=100 bp and discard everything shorter. For amplicons between 70 and 100 bp (e.g., short RT-qPCR products or miRNA amplicons), use a kit with an extended lower size limit -- the Thermo Fisher GeneJET kit retains fragments from 25 bp to 20 kb, covering this range. For amplicons shorter than 25 bp, conventional silica-column cleanup will not work; use gel purification or size-selective bead cleanup (e.g., AMPure XP at adjusted bead ratios).
Minimum Elution Volume
If the downstream application requires a high DNA concentration (Sanger sequencing needs &gt;20 ng/ul input), select a kit that elutes in as little as 20-25 ul without significant yield loss.&nbsp;
pH Indicator
Kits include a pH indicator dye in the binding buffer that turns yellow when the pH is correct for DNA binding and remains orange/red if the pH is too high (causing DNA loss). This is useful when purifying PCR products amplified in high-pH buffers. Kits without pH indicators require careful attention to binding buffer volume ratios to ensure efficient DNA adsorption.
96-Well Throughput
For screening workflows producing multiple amplicons per sample, use 96-well PCR purification plates with vacuum manifolds for simultaneous processing of all 96 wells. 96-well formats are essential for high-throughput genotyping and sequencing library preparation pipelines.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Key benchmarks for PCR cleanup kits: &gt;=70% DNA recovery for fragments 100 bp-10 kb, A260/A280 &gt;= 1.7 in eluate, complete removal of primers and dNTPs (confirmed by capillary electrophoresis with no peaks below 100 bp), and elution in &lt;=50 ul of water or TE. The Thermo Scientific GeneJET PCR Purification Kit specifies recovery rates up to 100% with a binding capacity of 25 ug per column in a 5-minute protocol. AAT Bioquest study comparing commercial PCR cleanup kit performance confirmed that silica-column kits consistently achieve primer and dimer removal equivalent to ethanol precipitation with significantly reduced protocol time. PCR cleanup is a mandatory step before NGS library preparation in nearly all sequencing-based workflows at institutions, including Howard Hughes Medical Institute, Vanderbilt University, and MD Anderson Cancer Center, where primer and dimer contamination in libraries produces low-complexity sequencing reads that reduce effective coverage.

<h2 dir="ltr">What Are Lentiviral Control &amp; Reporter Constructs?</h2>
 Rigorous experimental design requires matched controls that enter the same delivery workflow as the test construct. Lentiviral control and reporter constructs use the same vector backbones, promoters, and packaging systems as experimental vectors &mdash; ensuring observed differences between treated and control cells reflect genuine biological effects rather than artefacts of the delivery process.

</ul>
<h2 dir="ltr"> How to Choose Control &amp; Reporter Constructs</h2>
 Control Type Needed Empty vector controls carry only the selection marker (puromycin, blasticidin, or hygromycin resistance) without a gene of interest, providing the baseline reference for overexpression or knockdown experiments. Fluorescent Reporter Channel GFP and RFP lentiviral reporters allow real-time monitoring of transduction efficiency by flow cytometry or fluorescence microscopy, matching the experimental construct's promoter for an accurate expected-expression reference. Luciferase Reporter Pairing Firefly luciferase (P. pyralis) and Renilla luciferase (R. reniformis) are the two most commonly paired reporters; because they use different substrates (D-luciferin and coelenterazine, respectively), both signals can be measured sequentially from the same sample. Promoter-less Baseline A promoter-less dual luciferase control vector provides a no-promoter baseline against which promoter-driven reporter constructs are normalised &mdash; useful for establishing background signal levels. Vector Backbone Matching Using a matched vector backbone ensures observed differences between experimental and control cells are due to the transgene, not differences in vector, promoter strength, integration preference, or selection marker. 
<h2 dir="ltr"> Specifications Context</h2>
 Because lentiviral integration is heritable, transduced cells maintain stable reporter gene expression across cell divisions &mdash; stable luciferase or GFP reporter cell lines generated this way are widely used in drug screening, pathway activation assays, and long-term in vivo imaging. Through ABM, MBP can supply promoter-reporter lentiviral constructs covering human and mouse promoters, driving firefly luciferase or GFP expression, as plasmid DNA or pre-packaged particles. Both plasmid and pre-packaged formats are available for immediate dispatch, with institutional account pricing available for core facilities. Core facilities managing reporter constructs across multiple research groups often standardise on a small set of validated control vectors to simplify inventory and ensure consistency across projects.&nbsp;

Cryogenic Vials

<h2>What Are Cryogenic Vials?</h2>
&nbsp;
Cryogenic vials are specialized screw-cap laboratory containers manufactured from cryogenic-grade virgin polypropylene (PP) and designed to withstand extreme temperatures ranging from &minus;196&deg;C in liquid nitrogen storage to +121&deg;C during steam autoclaving. They serve as the primary storage vessel for biological materials requiring long-term preservation, including cell lines, serum, plasma, blood samples, DNA, RNA, microbial cultures, and other biospecimens. Common vial capacities include 1.2 mL, 1.5 mL, 1.8 mL, 2 mL, 3 mL, and 5 mL, with the 2 mL format being the most widely used standard for cell culture and biobanking applications. Most cryogenic vials feature leak-resistant screw caps with silicone sealing gaskets and dedicated writing areas for sample identification. For storage in liquid nitrogen, it is important to use vials specifically certified for cryogenic applications, as standard laboratory tubes are not designed to tolerate temperatures as low as &minus;196&deg;C.

</ul>
&nbsp;
<h2>How to Choose Cryogenic Vials</h2>
&nbsp;
Thread Type: Internal vs. External
Thread design influences both contamination control and workflow compatibility. Internal-thread vials position the sealing mechanism inside the neck of the vial, reducing the external surface area exposed to contaminants and making them a common choice for cell culture and biosafety-sensitive applications. External-thread vials place the threads on the outside of the vial neck, maximizing internal storage volume and improving compatibility with automated capping, decapping, and robotic handling systems. Laboratories using automated biobanking workflows often prefer external-thread formats.
Volume Selection
Vial capacity should match the intended sample type and storage requirements. The 1.8&ndash;2.0 mL size is commonly used for cell lines, serum aliquots, and general biospecimen storage because it fits standard cryogenic storage boxes. Smaller 1.2 mL formats support high-density storage of limited-volume samples, while larger 3&ndash;5 mL vials are suitable for tissue specimens, bacterial glycerol stocks, and applications requiring larger sample volumes.
Sterility and Purity Certification
For cell culture, molecular biology, and clinical research applications, cryogenic vials should be supplied with certifications confirming they are RNase-free, DNase-free, non-pyrogenic, and endotoxin-free. Many laboratories also prefer gamma-sterilized vials, which reduce contamination risk and eliminate the need for additional sterilization before use. Traceable lot documentation and certificates of conformity are often required in regulated environments.
Self-Standing vs. Round Bottom Designs
Self-standing cryogenic vials feature a molded base that allows them to remain upright on laboratory benches without additional support, reducing the risk of spills during sample handling. Round-bottom designs are compatible with a broader range of storage racks and cryogenic systems but generally require a rack or holder during bench-top use. The choice largely depends on laboratory workflow and storage equipment.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Cryogenic vials are typically manufactured from high-purity polypropylene because of its excellent durability and resistance to ultra-low temperatures. Products intended for liquid nitrogen immersion should carry explicit certification for liquid-phase storage, as some vials are approved only for vapor-phase applications. Vial dimensions, particularly outer diameter, determine compatibility with freezer boxes, racks, and automated storage systems, so measurements should be confirmed before mixing products from different manufacturers. Modern biobanking facilities increasingly use externally threaded, 2D-barcoded cryogenic vials integrated with laboratory information management systems (LIMS) to improve inventory tracking, sample traceability, and large-scale repository management.

Transfer Pipettes

<h2>What are disposable transfer pipettes?</h2>
&nbsp;
Disposable transfer pipettes are single-use plastic liquid-handling tools made from low-density polyethylene (LDPE). They are designed as a one-piece bulb-and-stem system used for transferring, dispensing, and handling small volumes of liquids in laboratory workflows.
They are commonly used as a safer and more convenient alternative to glass Pasteur pipettes. Being plastic and disposable, they eliminate the risk of breakage, reduce cross-contamination, and remove the need for separate rubber bulbs. The flexible bulb allows controlled aspiration and dispensing of reagents, samples, and solutions.
&nbsp;
<h2>What you will find:</h2>
&nbsp;
<ul>
<li>Graduated transfer pipettes &ndash; for approximate volume measurement and controlled dispensing</li>
<li>Non-graduated transfer pipettes &ndash; for simple liquid transfer without measurement markings</li>
<li>Fine-tip transfer pipettes &ndash; for small droplets and precise spot dispensing</li>
<li>Sterile transfer pipettes &ndash; for microbiology and contamination-sensitive workflows</li>
<li>Non-sterile transfer pipettes &ndash; for routine laboratory use</li>
<li>Disposable Pasteur pipettes &ndash; for general single-use liquid handling</li>
</ul>
&nbsp;
<h2>How to choose transfer pipettes</h2>
&nbsp;
Tip style Fine-tip pipettes are used for precise work such as microplate spotting and small-volume handling. Standard tips are suitable for general transfers, while wide-bore designs are better for viscous liquids or blood samples. Longer stems help access deep containers.
Capacity and volume handling Select pipettes based on typical working volumes. Smaller pipettes are suitable for low-volume transfers, while larger ones are used for routine sample handling. The effective draw volume depends on bulb capacity and usage technique.
Graduated vs non-graduated Graduated pipettes allow approximate volume estimation and are useful in clinical and diagnostic workflows. Non-graduated pipettes are intended for general dispensing where precise measurement is not required.
Sterility requirements Sterile pipettes are used in microbiology, cell culture, and clinical applications where contamination control is essential. Non-sterile versions are suitable for general laboratory and teaching use.
Length and accessibility Long pipettes are preferred for deep vessels such as flasks and bottles, while shorter designs are used for compact tubes and small workspaces.
&nbsp;
<h2>Specifications context</h2>
&nbsp;
Disposable LDPE transfer pipettes are widely used laboratory consumables for general-purpose liquid handling in research, clinical, and educational environments. They are available in sterile and non-sterile formats with multiple tip designs and capacities to support different workflows.
These pipettes remain a standard alternative to glass Pasteur pipettes due to their safety, low cost, and reduced contamination risk in routine laboratory applications.

PCR Tubes

<h2 data-path-to-node="1"> What Are PCR Tube Racks?</h2>
 PCR tube racks are polypropylene holders that maintain 0.2 mL PCR tubes and strip tubes in a stable 8&times;12 (96-position) upright array during reaction setup, pre-PCR storage, and post-amplification handling. They stabilise tubes during multichannel pipetting, prevent tip deflection when dispensing with an 8-channel pipette, and serve as organisational tools for pre- and post-PCR sample management. Most racks accept both individual 0.2 mL tubes and 8-strip or 12-strip tubes in the same 96-well footprint.&nbsp;

 Well Diameter and Tube Compatibility Standard 96-well PCR racks have a 5.2 mm well diameter, compatible with most 0.2 mL thin-wall PCR tubes from Globe Scientific, Nest Scientific, Axygen/Corning, Eppendorf, and equivalent brands. Confirm the collar diameter of your specific tube brand before ordering if using non-standard tube geometry. Lid: Hinged Flat vs Translucent Cover vs No Lid Hinged flat lids lie flush when open for unobstructed pipette access; the lid can be closed to protect tubes during incubation or transport. Translucent polycarbonate lids allow visual sample inspection without lid removal &mdash; useful for barcode readers that scan through the cover. Lidless racks are the simplest format for bench use, where brief sample exposure is acceptable. Colour Coding Racks are available in single colours (blue, green, pink, yellow, orange) and assorted multi-colour packs. Colour-coded racks help segregate pre-PCR and post-PCR samples, reducing cross-contamination risk in labs without fully separated pre/post-PCR workspaces. Autoclavability Polypropylene PCR tube racks are autoclavable at 121&deg;C (250&deg;F) for sterilisation between use cycles. Polycarbonate lids withstand repeated autoclave cycles at standard sterilisation conditions. SBS Footprint for Automation Select PCR strip racks with an SBS/SLAS-compliant footprint (127.76 &times; 85.47 mm) to enable use with robotic liquid handlers and automated workstations when processing strip tubes on automation platforms.

 Standard 96-well PCR tube racks measure approximately 130 &times; 98 &times; 33 mm (L &times; W &times; H) with 5.2 mm well diameter and 9 mm well spacing. Polypropylene construction is chemical-resistant and autoclavable at 121&deg;C. Alphanumeric embossed grid (A&ndash;H rows, 1&ndash;12 columns) matches the labelling of PCR plates and plates for straightforward sample mapping. SP Bel-Art 96-well PCR racks and equivalent formats from Heathrow Scientific and Globe Scientific are widely distributed in North American research labs.&nbsp;

PCR Tube Racks

<h2 dir="ltr">What Are Individual PCR Tubes?</h2>
 Individual PCR tubes are single-reaction thin-wall polypropylene vessels supplied separately rather than in strip or plate format. The 0.2 mL format is the global standard for modern thermal cyclers with conventional 96-well block geometry, while 0.5 mL tubes are used with older or specially adapted blocks. Individual tubes offer the flexibility to set up any number of reactions without being constrained to a strip of 8 or 12, making them ideal for one-off reactions, optimisation runs, and protocols requiring varied tube counts. Choose individual tubes for variable reaction counts and when colour-coding samples matters.

 Volume: 0.2 mL vs 0.5 mL The 0.2 mL tube fits virtually all modern thermal cycler blocks, including Bio-Rad T100, Eppendorf Mastercycler NEO, and Applied Biosystems Veriti. The 0.5 mL tube is used with specific gradient blocks or older instruments; confirm block compatibility before ordering this format. Attached Cap vs No Cap Tubes with attached dome caps offer convenience and prevent cap mix-ups during high-volume workflows. Tubes with flat attached caps or sold without caps (requiring separate cap purchase) are chosen when flat optical caps or coloured caps are needed for tube tracking. Colour Options Coloured individual tubes (clear, white, yellow, red, blue, green) allow colour-based sample tracking without labelling, particularly useful in high-throughput genotyping or multiplex PCR workflows where visual differentiation reduces setup errors. Polypropylene Grade Individual tubes should be moulded from virgin polypropylene free of additives, antistatic agents, and dyes that can inhibit PCR enzyme activity. White tubes (for qPCR with fluorescence read from the bottom) must use a white polypropylene body that maximises signal reflection. 
<h2 dir="ltr"> Specifications Context</h2>
