Chitosan is labeled with fluorescein (FITC), Ex/Em wavelength 494/518 nm. Purity: >95% powder. Standard Degree of substitution (DoS): 1 mol % substitution and at least one dye 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.
