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. omics2view.consulting GbR are proud to offer its customers standardized, reliable analyses at the ASV level to gain a better understanding of biological and medical implications.
