small intestine mucin galactosyltransferase activity was purified 800-fold using a series of ion exchange ( deae-sepharose ) , gel filtration ( s-200 sephacryl ) and affinity chromatographic steps to isolate the mucin galactosyltransferase activity from a triton x-100/nonidet p-40 extract of homogenized cells obtained by scraping everted intestines .
