Chitosan is labeled with both biotin and fluorescein, Ex/Em wavelength 494/518 nm. Purity: >95% lyophilized powder. Standard Degree of substitution: 1 mol % substitution for each dye and at least one biotin and one fluorescein molecule per polymer. Chitosan labeled with other types of fluorescent dyes may be offered through our custom synthesis.


Chitosan is produced by deacetylation of chitin, which is the structural element in the exoskeleton of crustaceans (such as crabs and shrimp) and cell walls of fungi. The degree of deacetylation (%DD) can be determined by NMR spectroscopy from 60 to 100%.Chitosan products are characterized by either its MW or its viscosity. The amino group in chitosan has a pKa value of ~6.5.
