Phytohemagglutinin: Inhibition of the Agglutinating Activity by <i>N</i> -Acetyl-D-Galactosamine

Abstract

The effect of simple sugars on the agglutinating activity of phytohemagglutinin was studied. N-Acetyl-d-galactosamine selectively inhibits the agglutination of leukocytes and erythro- cytes by phytohemagglutinin.
