Application
The enzyme has been used to study the consequences of inducing acute, long-lasting changes in chondroitin sulfate proteoglycans using adult rat brain cells.[1] Glycosaminoglycans have been digested with chondroitinase ABC for chondroitin/dermatan sulfate quantitation in keratocyte cell cultures obtained from fresh bovine corneal stromae.[2]
Biochem/physiol Actions
Chondroitinase ABC catalyzes the eliminative degradation of polysaccharides containing (1-4)-β-D-hexosaminyl and (1-3)-β-D-glucuronosyl or (1-3)-α-L-iduronosyl linkages to disaccharides containing 4-deoxy-β-D-gluc-4-enuronosyl groups. It acts on chondroitin 4-sulfate, chondroitin 6-sulfate, and dermatan sulfate, and acts slowly on hyaluronate. The molecular weight is found to be approximately 120 kDa with 2 non-identical subunits of molecular masses 86 kDa and 32 kDa. The pH optimum is found to be 8.0 with chondroitin sulfate and 6.8 with hyaluronic acid and temperature optimum is 37 °C. 1 mM Zn2+ acts as an inhibitor, while 0.05 M acetate is an activator of the enzyme.

Could you provide specific data regarding the pH-dependent activity of Chondroitinase ABC (Product No. C3637)? I am particularly interested in how the enzymatic activity changes between pH 7.0 and pH 8.0.
1 answer-
This product shows maximal enzymatic activity on chondroitin sulfate at approximately pH 8.0, based on assay conditions at 37 °C. At pH 7.0, the enzymatic activity rate is significantly lower. The pH-activity profile indicates activity peaks at pH 8.0 and decreases to less than 40% when the pH falls below 7.0, indicating a steep decline. For hyaluronan, the optimal pH is approximately 6.8. Please see the link below to review additional information available in the product datasheet:

Good evening, in which solution has to be solubilized the product? Thanks a lot, Sara
1 answer-
This product should be reconstituted in a 0.01% BSA aqueous solution. Subsequent dilutions can be made into a buffer containing 50 mM Trizma® HCl, pH 8.0, with 60 mM sodium acetate and 0.02% BSA Prepare solutions just prior to use. More product details are available under "More Documents" or at this link: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/product/documents/399/066/c3667pis-ms.pdf
