Biochem/physiol Actions
PNA does not agglutinate normal human erythrocytes, but strongly agglutinates neuraminidase treated erythrocytes. PNA has potent anti-T activity similar to the anti-T antibody in human sera. The lectin can be used to distinguish between human lymphocyte subsets.
Lectin from Arachis hypogaea (peanut) functions as an antigenic determinant for Thomsen-Friedenreich antigen (TF) and as mitogen for colorectal cancer stimulation cell division in normal colonic epithelium. It is therefore used as tumor marker.
General description
Peanut lectin (PNA) is a lectin or an agglutinin from the legume, Arachis hypogaea, found in peripheral venous blood in humans after ingestion of peanuts. PNA lectin is specific to the galactosyl (?-1,3) N-acetylgalactosamine.
