WebMar 3, 2016 · Electrophoresis was performed in 12.5% acrylamide gel containing glycol chitosan (B) or glycol chitin (C). Chitosanase or chitinase activity was detected by Calcofluor White M2R staining after the lysis of glycol chitosan or glycol chitin in the gel. Lane M contains the protein molecular weight marker; lane 1 contains purified chitosanase. WebJan 1, 1988 · The chitin deacetylase activity is assayed by measuring the radioactivity of [ 3 H]acetic acid liberated from a water-soluble chitin derivative, glycol [acetyl- 3 H]chitin. The enzyme can liberate the N-acetyl groups from N-acetylglucosamine residues in glycol chitin, a water-soluble chitin derivative. The limit of deacetylation is as low as ... WebMar 22, 2024 · Then, 200 mL of 70 mM potassium phosphate pH 6 was added and colloidal chitin concentration was estimated by titrating the weight of solute contained in 1 mL of solution that was previously frozen at − 70 °C and lyophilized.
