<h2>What are microbiome standards and controls?</h2>
&nbsp;
Microbiome standards and controls are defined reference materials, ranging from a single microbial DNA standard to a complex mock community containing multiple known bacterial, fungal, or archaeal species at defined relative abundances, used to validate that an extraction, library preparation, and sequencing pipeline is performing as expected. Running a standard alongside real samples provides a specific, customized control for confirming reproducibility and enables meaningful comparison of results generated in different laboratories or at different times.

<h2>How to choose microbiome standards and controls</h2>
&nbsp;
Match standard complexity to your validation goal
A single-species microbial DNA or inactivated bacteria standard is sufficient for confirming basic assay sensitivity or specificity, while a multi-species mock community standard with defined relative abundances is needed to evaluate extraction and amplification bias across an entire workflow.
Use a standard to benchmark a new extraction or library prep protocol
Running a known mock community through a new or modified extraction and library preparation protocol, then comparing the resulting sequencing output against the standard's defined composition, reveals whether the new protocol introduces meaningful bias compared with an established method.
Confirm whether your standard supports both DNA-based and RNA-based workflows
Some standards are formulated specifically for DNA-based 16S or shotgun metagenomic workflows, while others, or specific lots, are validated for RNA extraction and metatranscriptomic workflows as well, a distinction worth checking against your specific application.
Include a standard when comparing results across different laboratories
Because microbiome sequencing results can be sensitive to differences in extraction method, primer choice, and sequencing platform between labs, including the same reference standard across collaborating sites supports more reliable comparison of results generated independently.
Confirm standard storage and stability before long-term use
Microbial community standards typically have documented stability windows and storage temperature requirements, and confirming these align with your intended use timeline helps avoid degraded standard material producing misleading validation results.
&nbsp;
<h2>Specifications context</h2>
&nbsp;
Individual microbial DNA and inactivated bacteria standards add value specifically by providing a specific, customized control, supporting both microbiomics and metagenomics workflows by increasing reproducibility and allowing reliable comparison of results from different laboratories. As of 2026, defined mock community standards remain a standard tool for benchmarking new extraction or library preparation protocols against established methods before adopting a new workflow for real sample processing.

Varizymes MS2 Phage

MS2 Phage by Varizymes is a Biosafety Level 1 single-stranded RNA bacteriophage used as an internal and process control for RNA extraction, RT-PCR and RT-LAMP. Its 3,569-nucleotide genome is packaged in a protein capsid, so it tracks the full workflow from lysis to amplification. Assay labs can order 1×10⁹ or 5×10¹⁰ PFU from MBP with certificates of analysis for each lot.
