abstract：:A new bacterial agglutinin was isolated from seeds of the soybean cultivar Clark. Purification was carried out by ammonium sulfate precipitation and ion-exchange chromatography. The agglutinin is a heat-labile glycoprotein most active at pH 4.0. Addition of Ca(2+), Mn(2+) and Mg(2+) did not enhance the agglutinating a...
