InstantAB Labeled Glycans
AdvanceBio InstantAB Bovine fetuin N-glycan library (formerly ProZyme). Library is composed of a mixture of sialylated N-linked glycans (core non-fucosylated), consistent with N-glycans previously reported for bovine fetuin. The biantennary glycans can have one or two of the sialic acid residues (NeuAc); the triantennary glycans can have from one to four of the sialic acid residues. The sialic acid residues are found in both α(2,3) and α(2,6) linkages. Triantennary glycans constitute ~85% of total glycans present. A small amount of penta-sialylated glycans can be detected, but their structure has not been determined. The reducing termini are derivatized with the fluorescent dye, InstantAB.
