Abstract
Rat fibrinogen plasmic fragment E was found to contain one oligosaccharide chain per gamma-chain attached by a glycosylamine linkage. The oligosaccharide was composed of 1 sialic acid, 1 galactose, 2 mannose and 2 glucosamine residues. The probable sequence from the nonreducing end was sialic acid leads to galactose beta leads to mannose alpha leads to mannose alpha leads to glucosamine leads to glucosamine. No difference in the rate of clearance from the rat circulation could be detected between native and desialated fragment E. A non-denaturing method for the purification of fragment E is described.
