The A2 & A2F family of glycans includes all biantennary glycans, including the core (1-6) fucosylation and non-fucosylated biantennary glycans found on many IgG and other mammalian glycoproteins.
The A3 family of glycans (A3, NGA3, and NA3) are naturally occurring N-linked oligosaccharides conjugated to a wide range of mammallian and recombinant glycoproteins.
A4 family glycans with the tetra-antennary NA4 glycans as either a core or parent structure are naturally found as N-linked oligosaccharides conjugated to alpha-1 acid glycoprotein (AAGP).
Includes the MAb4 Antibody reference panel, O-linked Core 1 glycan, and our alpha gal standard. Also included here are the hybrid glycan, fetuin glycoprotein standard, and our Carboladder.
2-AA is considered by many to be a superior replacement for 2-AB (2-aminobenzamide) in most types of complex glycan analysis. 2-AA is reported to have a higher fluorescence and gives higher labeling efficiencies than 2-AB.
