It has been previously observed that rabbit erythrocyte cell surface galactosyltransferase appears to play a role in concanavalin A agglutination of these erythrocytes (Podolsky et al., 1974). Further, a correlation between the occurrence or level of cell surface galactosyltransferase and concanavalin A agglutinability of other cell types has also been observed. The mechanism by which rabbit er...

Concanavalin A, a protein isolated from the jack bean (Canavalia ensijormis), has previously been shown to form a precipitate with glycogen and yeast mannan, and more recently with dextrans and amylopectin. Double-diffusion precipitation studies in agar gel have been found to afford a very sensitive and satisfactory method for investigating the interaction of concanavalin A with certain types o...
