the structure of the hybrid was established by bio-gel p-4 fractionation of oligosaccharides produced by endoglycosidase h treatment of pronase-derived glycopeptides , followed by examination of the susceptibility of the oligosaccharide to glycohydrolases and by its adsorbability to serotonin-sepharose 4b .
