PMS2 (Postmeiotic Segregation Increased 2) is a DNA repair protein involved in mismatch repair. SensiStain Anti-Recombinant PMS2 Antibody was developed alongside MLH1, MSH2, and MSH6 to complete our MMR-series for research use. PMS2 expression levels may be used theorectically as a screening tool for Lynch syndrome after a colorectal cancer diagnosis.
