Potato lectin of specific agglutinating activity of 10,000 units per mg was isolated. Chemical modifications of potato lectin with acetic and succinyl anhydrides or N-acety-limidazole result in complete loss of agglutinating activity. The lectin after reduction of disulfide bonds with dithiothreitol shows 25% of the native agglutinin activity. These results suggest that amino and phenolic groups are involved in the reaction of potato lectin with erythrocytes.
