The Idylla MSI Test, for use on the Idylla System, uses formalin-fixed, paraffin embedded (FFPE) tissue sections of human CRC tumor, from which nucleic acids are liberated, then analyzed using PCR amplification of seven monomorphic biomarkers (ACVR2A, BTBD7, DIDO1, MRE11, RYR3, SEC31A and SULF2) and subsequent melt-curve analysis. The Idylla MSI Test reports results as either microsatellite stable (MSS), or microsatellite instability high (MSI-H) or invalid.
A collection of reagents and other associated materials intended to be used for determining microsatellite instability [abnormal repeated sequences of deoxyribonucleic acid (DNA)] within a tumour tissue specimen, using a nucleic acid technique (NAT). This phenomenon which is associated with defective DNA mismatch repair genes is a feature of certain cancer types including hereditary nonpolyposis colon cancer (HNPCC).
