&nbsp;
Cloning chemicals and reagents cover the enzymes, buffers, and molecular biology-grade chemicals used in DNA fragment preparation, modification, and purification within a cloning workflow, including restriction endonucleases, T4 DNA ligase and other DNA-modifying enzymes (phosphatases, polymerases), reaction buffers, and plasmid extraction reagents. Related entities include restriction enzyme digestion, DNA dephosphorylation/phosphorylation, plasmid DNA purification (column-based and magnetic bead-based), and enzyme unit definitions.

&nbsp;
Restriction enzyme selection and buffer compatibility
Restriction enzymes require specific reaction buffers, and many modern enzyme lines use a single universal buffer compatible across multiple enzymes to simplify double-digest reactions; confirm buffer compatibility when combining enzymes from different suppliers or using older single-buffer-per-enzyme formulations.
Enzyme unit definitions and reaction scale
Restriction enzyme and ligase activity is defined in units per microliter, with one unit typically defined as the amount needed to digest or ligate a defined quantity of standard substrate DNA under specified conditions in a set time; scale enzyme quantity to the amount of DNA being processed rather than assuming a fixed volume works for all reaction sizes.
Plasmid purification grade
Plasmid DNA extraction reagents range from molecular biology grade, suitable for general cloning and sequencing, to transfection-grade or endotoxin-free formulations required for applications such as lentiviral packaging or mammalian cell transfection, where endotoxin contamination can reduce transfection efficiency or cause cell stress.
Dephosphorylation for preventing vector self-ligation
Alkaline phosphatase treatment of a linearized vector before ligation removes 5' phosphate groups, preventing vector self-ligation and improving the ratio of recombinant clones; this step is particularly useful when the vector and insert share compatible sticky ends that could otherwise religate without insert incorporation.

&nbsp;
Restriction enzymes and ligases are supplied at defined unit concentrations (commonly 10&ndash;20 units per microliter for restriction enzymes), with reaction buffers formulated for specific pH and salt conditions optimized for enzyme activity. Plasmid purification kits are differentiated by yield (micrograms of DNA recovered), purity (A260/A280 ratio), and endotoxin level (endotoxin units per microgram), with endotoxin-free kits specifying levels below a defined threshold suitable for transfection applications.&nbsp;
This sub-category is part of MBP's cloning catalog alongside ligation independent cloning kits and transformation kits and competent cells, used downstream of enzyme-based fragment preparation. Labs producing custom lentivirus for immortalization can also review MBP's cell immortalization catalog. MBP's specialist team can help confirm enzyme buffer compatibility and plasmid purification grade for a specific downstream application before order placement.
