WebMethods of Detection. There are several methods that can be used to detect microsatellite instability (MSI) or deficient DNA mismatch repair (dMMR). The two most common methods are polymerase chain reaction (PCR) and immunohistochemistry (IHC). MSI testing by PCR is the accepted gold standard method for MSI detection (1).

"WebThe proportion of dominant microsatellites detected in this study (close to 50 %) was much higher than that commonly reported in many other studies. A high proportion of dominant markers together with a high frequency of codominant markers with null alleles may represent two important limitations for the use of microsatellites in different studies.
