Q: What is the definition for Labeling Degree (%) of your fluorescently-labeled dextran products?
A: Labeling Degree (%) is determined by dividing the number of covalently conjugated fluorescent dye by the total number of monomeric units of a polysaccharide molecule chain. For instance, 1.0 MOL % labeling means that one of every one hundred monomeric units along the polysaccharide chain is fluorescently labeled.
