Microsatellite Instability Assay for Response to Immunotherapy

MSI assay for sensitive detection of 5 mononucleotide repeat markers in tumor FFPE specimens
Home / Insights / Microsatellite Instability Assay for Response to Immunotherapy

Available within our comprehensive immuno-oncology assay portfolio, IQVIA Laboratories’ MSI assay utilizes multiplex, fluorescent PCR and capillary electrophoresis to enable sensitive detection of five mononucleotide repeat markers (BAT-25, BAT-26, NR-21, NR-24 and MONO-27) in tumor FFPE specimens. Microsatellite instability at two or more mononucleotide loci is interpreted as MSI-High; microsatellite instability at a single mononucleotide locus is interpreted as MSI-Low; no instability at any of the loci tested is interpreted as microsatellite stable (MSS). The MSI assay has been analytically validated and is available for Research Use Only applications.
