5 units in serum bottle

Preparation Note

Reconstitute the product in 20 mM phosphate buffer, pH 7.0. Subsequent dilutions can be made with a 0.01% aqueous bovine serum albumin solution.

Unit Definition

One unit will cause a ΔA232 of 1.0 per minute due to the release of unsaturated disaccharide from chondroitin sulfate A at pH 7.3 at 37 °C. Reaction volume: 3.1 ml (light path 1 cm).


Chondroitinase AC from Sigma has been used for the large scale preparation of glycosaminoglycan (GAG) fractions during the study of structural and sequence motifs in dermatan sulfate.

Biochem/physiol Actions

Chondroitinase AC from Flavobacterium heparinum is an enzyme that cleaves sulfated and non-sulfated polysaccharide chains with (1-4) linkages between hexosamines and glucuronic acid residues, by an elimination mechanism. The resulting oligosaccharide products are mainly disaccharides with unsaturated uronic acids. Chondroitinase AC specifically degrades chondroitin sulfates A and C, but not chondroitin sulfate B (dermatan sulfate).


Depending on reaction conditions, digestion of chondroitin sulfate may result in hydrolysis of disaccharides
