This antibody labels the MutL homolog 1 (MLH1) protein in the nucleus of normal proliferating cells in both normal and neoplastic tissues and does not stain colon adenocarcinoma with complete loss of MLH1 expression. MLH1 is a useful tool for classifying tumors of the gastrointestinal tract, including associated extra colonic cancers such as endometrial and prostate cancers, when used in a panel of antibodies.
