the terminal galactose of underivatized type 2 chain structures is removed by hydrolysis with jack bean beta-galactosidase followed by transfer of galactose in beta 1 -- -- 3 linkage catalyzed by a beta 1 -- -- 3-galactosyltransferase from human colonic adenocarcinoma colo 205 cells which was first depleted of beta 1 -- -- 4-galactosyltransferase by chromatography on alpha-lactalbumin-sepharose .
