Identification and isolation of an agglutinin from uterus of rats.
A sialic acid-binding agglutinin was purified to apparent homogeneity by affinity chromatography on fetuin-sepharose column from the rat uterine homogenate in estrus. The agglutinin is Ca++ dependent, a glycoprotein, and composed of two very closely associated bands of molecular weights 28,000 and 30,000 and pIs of 4 and 4.1. Several sialoglycoproteins, sialic acid, EDTA, glucuronic acid and heparin acted as an inhibitor of the agglutinin.
