The average read-out from conventional bulk sequencing misses the rare events and underlying genetic diversity within and across cell populations. The Tapestri Platform is the first and only single-cell platform to simultaneously detect Copy Number Variants (CNVs) and Single Nucelotide Variants (SNVs) from the same cells. To resolve heterogeneity and improve patient stratification, therapy selection, and disease monitoring we need to detect rare clonal populations and identify co-occurrence and zygosity within every single cell.
