Product Description
Measuring how well a sequencing pipeline detects rare taxa requires a reference with very uneven, precisely known abundances. This Zymo Research DNA standard supplies exactly that, offering a log-distributed genomic DNA mix that lets labs evaluate sensitivity and quantitative accuracy from library prep onward. It is a practical companion to cellular mock communities.
This listing is for catalog number D6311: ZymoBIOMICS Microbial Community DNA Standard II, Log Distribution. It is built by quantifying genomic DNA from pure cultures of eight bacteria and two fungi, pooling them at log-stepped ratios and confirming the final composition by NGS. Impurity is below 0.01%. Because the DNA is already extracted, the standard isolates library preparation, sequencing and analysis performance, and it works well as a routine QC positive control. Add it to your LIGHT LABS order and keep your bench stocked.
Key Features
- Log-stepped composition – Abundances range from 89.1% down to 0.000089%.
- NGS-verified – Composition is confirmed by sequencing after pooling.
- Very low impurity – Contains less than 0.01% contaminating DNA.
- Post-extraction control – Focuses on library prep, sequencing and bioinformatics steps.
- Bacteria and fungi – Combines eight bacterial and two fungal genomes.
