FAQs

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: 
1. 2-3/2-3/2-3 
2. 2-3/2-3/2-6 
3. 2-3/2-6/2-6 
4. 2-6/2-6/2-6
