Detection of terminal N-linked N-acetylglucosamine residues in the Golgi apparatus using galactosyltransferase and endoglucosaminidase F/peptide N-glycosidase F: adaptation of a biochemical approach to electron microscopy.

Abstract

Purified human milk beta-N-acetylglucosaminide beta 1, 4 galactosyltransferase (EC 2.4.1.38) was used to galactosylate N-acetylglucosamine (GlcNAc) residues present in ultra-thin sections of Lowicryl K4M-embedded rat and pig liver. Both endogenous galactose and galactosylated transferase products could be revealed by Ricinus communis lectin I-gold complexes… (More)
