resulted in the cleavage of 98–99% of the radioactivity from the protein. Of this, 63% of the radioactivity from epiglycanin and 70% from asialoepiglycanin co-migrated with an authentic sample of 2-acetamido-2-deoxy-3-O-(β- d -galactopyranosyl)- d -galactitol on a column of Bio-Gel P-6. Incubation of [3H]galactose-epiglycanin with endo-N-acetyl -α- d -galactosaminidase (Diplococcus pneumoniae), and fractionation
