TABLE 3.

Monosaccharide composition of the high-MW glycoconjugate fraction^a

Monosaccharideb	Amt of protein (nmol/mg)c	% by wt
Mannose	175 ± 25	2.8
Galactose	162 ± 19	2.6
Fucose	83 ± 16	1.2
N-Acetylglucosamine	Present but not quantitatedd	N/Ae

^aPooled material (fractions 18 to 20) from the gel filtration step of the purification was analyzed for protein content by colorimetric assay and monosaccharide content by GC-MS.

^bGlucose and a trace of xylose were also detected, but these are common contaminants of biological preparations and have been omitted from the table.

^cMeans and standard deviations of the results from triplicate analyses.

^dThe N-acetylglucosamine derivatives were positively identified by retention time and mass spectrum, but quantification of these derivatives is unreliable.

^eN/A, not applicable.
