Description
High purity Chitosan is extracted from Chitin. DDA: degree of deacetylation; cP: centipoise for dynamic viscosity. Chitosan has NH2 groups that can be used for bioconjugation or further derivatization using amide coupling reaction with carboxylic acid. Chitosan is not soluble in water but very soluble in 0.1% acetic acid due to the protonation of the amino groups leading to positively charged ammonium groups, which may be used in both amine bioconjugation or electrostatic interactions with negatively charged polymers or surfaces.
