It is recommended to reconstitute Chondroitinase ABC in a 0.1% BSA aqueous solution. Solubilizing 2 units in a 2 mL volume will result in a concentration of 2 units/mL or 0.002 units/µL.

애플리케이션
Chondroitinase ABC from Sigma has been used to digest O-linked chondroitin sulfate-like glycosaminoglycan (CSGAG).[1] The enzyme has also been used to digest glycosaminoglycan chains in proteoglycans during the construction and expression of a recombinant versican gene in mammalian systems.[2] Furthermore, it has been used to digest chondroitin sulfate in the proteoglycan complexes.[3] The enzyme has also been used in the removal of glycan chains from aggrecan, which eliminates the axon growth-inhibitory effect of aggrecan.[4]
생화학적/생리학적 작용
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. However, it acts slowly on hyaluronate. The molecular weight is approximately 120 kDa with 2 non-identical subunits of molecular masses 86 kDa and 32 kDa. The pH optimum is 8.0 with chondroitin sulfate and 6.8 with hyaluronic acid. The optimal temperature is 37 °C. 1 mM Zn2+ acts as an inhibitor, while 0.05 M acetate is an activator of the enzyme.
