N-acetylneuraminic acid (Neu5Ac or NANA) quantitative standard, 1 nmol

The Sialidase Testing Panel contains a mixture of α2-3, α2-6, and α2-8 sialylated oligosaccharides labelled with either 2-AB or procainamide. They were developed as a process control for sialidase digestions. Applied alongside the samples, it demonstratesshows that the enzymes have the expected specificity.

Sialylated Core 1 Glycan, The sialylated core 1 glycan has one terminal NeuAc sialic acid linked α-3 to the galactose of the core 1 glycan, sialylated-Tn antigen, 10 µg.

Procainamide labelled fucosylated, asialo, monogalactosylated biantennary oligosaccharide

The Fetuin Glycoprotein Standard was developed for use as a positive control during glycan release and labelling (particularly for DMB sialic acid analysis). Fetuin exists in a variety of glycoforms containing bi-, tri-, and tetraantennary N-linked oligosaccharides with variable sialylation, as well as O-linked glycans.
