Characterization of [9-3H] sialyl labeled glycopeptides obtained following pronase digestion
[9-3H] sialyl labeled Glycoprotein | [9-3H] sialyl label containing Biogel P6 fractions resulting from Pronase digestion | |
---|---|---|
Major Glycopeptide Fractions | Minor Glycopeptide Fractions | |
I. HCGβ: 31.4% and 10.2% respectively of the glycoprotein binds ConA- and AAL- whereas 100% of it bound WGA-agarose | Four: the largest size one binding to WGA-agarose and the smallest size not binding to WGA-agarose. The middle two fractions contained both WGA binding, non-binding and loosely binding glycopeptides. | None |
II. MN Glycophorin A | One: binding to WGA-agarose and not binding to VVL-agarose | None |
III. GlyCAM-1 | Two: the large size one binding to WGA-agarose; The small size one not binding to WGA-agarose | None |
IV.Fetuin: 100% of glycoprotein binds WGA-agarose | Two: both did not bind to WGA-agarose | One: mostly not binding to WGA-agarose |
V. Human placental glycoproteins: 98% bound to WGA-agarose | Two: apparently heterogenous | None |
VI. Bovine casein macroglycopeptide: 60% bound to WGA-agarose | One: large in size | One: small in size |
VII. Porcine Cowper's gland mucin | One: large in size | Two: smaller in size |
