BenchMark™ Microbial Amplicon Sequencing
Optimized Amplicon Sequencing
We pair our low-bias amplification method with an optimal closed-reference alignment to provide you with highly accurate data.
We offer BenchMark™ sequencing that targets the variable region 4 of the bacterial 16S rRNA gene, the fungal ITS2 region, and custom marker genes of your choice.
Eliminate Taxonomic Dropout
BenchMark™ combines real-time PCR sample quantification, dual-indexed multiplexing, and optimized enzymatic and PCR conditions to eliminate most of the taxonomic dropout that is observed with standard amplicon sequencing methods.
BenchMark™ suppresses chimera formation and minimizes PCR error, resulting in greater accuracy when tested head-to-head against other amplicon sequencing methods in the analysis of defined mock community standards.
In the plot below, the dotted line represents the expected percent abundance of each community member in a mock community. The BenchMark™ low-bias approach is highlighted in yellow.
Sample Types Suited for BenchMark™
Shotgun metagenomic sequencing is highly accurate, but isn’t best suited for all sample types.
Samples with low microbial loads benefit from the approach of amplifying and sequencing just a small portion of the microbial genome.
BenchMark™, our amplicon sequencing approach, is recommended for samples that have low biomass, including environmental samples such as soil and surface swabs.
We also recommend amplicon sequencing for samples with high amount of host DNA, such as skin swabs or biopsy samples.
Cost:Starts at $89/sample.
Minimum order:88 samples for 3-week turnaround, 24 samples for 6-week turnaround.

BenchMark™ sequencing starts at $89 a sample.
To ensure data of the highest quality, we require a minimum number of 24 samples per project.
To ensure your BenchMark™ samples return the best data, we recommend performing your DNA extraction at CoreBiome.
Input DNA quality and quantity can have dramatic impacts on the microbial profile generated for your samples.
By allowing the experts at CoreBiome to extract and prepare your DNA, we can ensure the best quality library preparations for amplicon sequencing.
CoreBiome accepts primary samples, such as swabs, fecal samples, and soil, as well as pre-extracted DNA.
