NEW! Amplicon Sequence Variant-Based Microbiome Analysis

In marker gene amplicon sequencing, microbial composition is derived from the abundance of amplicon sequences in the sample data. Traditionally, sequences within a certain similarity threshold were clustered into Operational Taxonomics Units (OTUs). The method of clustering and the value of the threshold have been controversial ever since. A more accurate alternative to the traditional OTU approach are Amplicon Sequence Variants (ASVs), which refer to sequences differing from each other by a single nucleotide. ASV-level analysis provides better resolution of microbial communities and enables accurate measurement of diversity. GbR are proud to offer its customers standardized, reliable analyses at the ASV level to gain a better understanding of biological and medical implications.
