6639963-2	1983	This method, which utilizes high performance liquid chromatography, distinguishes addition of sialic acid to the N-acetylgalactosamine vs. galactose residues of the mucin disaccharide Gal beta(1 leads to 3)GalNac, and can be used to distinguish formation of the 3"- and 6"-isomers of sialyllactose.	N-acetylgalactosaminuronic acid	206-212	mucin 1, cell surface associated	Bos taurus	165-170	
6639963-3	1983	For the bovine, ovine, and porcine submaxillary extracts, more than 95% of the activity with asialo ovine submaxillary mucin is due to formation of NeuAc alpha(2 leads to 6)GalNAc.	N-acetylgalactosaminuronic acid	173-179	mucin 1, cell surface associated	Bos taurus	119-124	
6639963-8	1983	The relative preference of the N-acetylgalactosaminide alpha(2 leads to 6) sialyltransferase for a monosaccharide vs. a substituted GalNAc may play a role in regulation of chain length during mucin synthesis.	N-acetylgalactosaminuronic acid	132-138	mucin 1, cell surface associated	Bos taurus	192-197
