Disaccharides 65-77 glycoprotein 2 Homo sapiens 301-305 2473980-3 1989 Gp-2 was one of the major fractions in the Pronase digest of a sea-squirt antigen, Gi-rep, and is capable of eliciting the skin reaction specific to patients with sea-squirt allergy similarly to Gi-rep. An additional disaccharide structure of GalNAc1----(3/4)HexNAc1---- was also expected as the other major non-reducing terminal unit, though the anomeric configuration of the terminal GalNAc could not be identified.
