Q. Can I use your unlabeled glycans with dyes that label glycosylamines?
We offer a range of InstantDye-labeled glycan standards to support glycoslyamine labels:
Q. What sialic acid linkages are contained within the product?
A. The product supplied is a mixture of isomers differing in the type of sialic acid linkages: α(2-3) or (2-6). A typical QC chromatogram shows 4 A3 peaks, representing 4 forms of A3 that differ in the way the terminal sialic acid is linked. Our assignments for the peak ID in order of elution:
