Packaging

2, 5, 10 units in glass bottle

Packages based on chondroitinase C activity.

Preparation Note

Reconstitute in a 0.01% bovine serum albumin aqueous (BSA) solution. Subsequent dilutions can be made into a buffer containing 50 mM Tris, pH 8.0, with 60 mM sodium acetate and 0.02% BSA. Solutions should be freshly prepared.

Unit Definition

One unit will liberate 1.0 μmole of 2-acetamido-2-deoxy-3-O-(β-D-gluc-4-ene-pyranosyluronic acid)-4-O-sulfo-D-galactose from chondroitin sulfate A or 1.0 μmole of 2-acetamido-2-deoxy-3-O-(β-D-gluc-4-ene-pyranosyluronic acid)-6-O-sulfo-D-galactose from chondroitin sulfate C per min at pH 8.0 at 37 °C.

Physical form

Lyophilized powder containing Tris buffer salts

Application

Chondroitinase ABC from Sigma has been used to digest O-linked chondroitin sulfate-like glycosaminoglycan (CSGAG). 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. Furthermore, it has been used to digest chondroitin sulfate in the proteoglycan complexes. The enzyme has also been used in the removal of glycan chains from aggrecan, which eliminates the axon growth-inhibitory effect of aggrecan.

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. 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.

What is the molecular weight of this enzyme (Product No. C2905)?
Chondroitinase ABC is a lyase with a reported molecular weight of approximately 120 kDa by gel filtration and is composed of two subunits with molecular weights of 86 and 32.
What is the composition of Product No. C2905?
This product consists of approximately 35% protein as determined by the Biuret method. BSA (bovine serum albumin) is a major component (~90%) of the protein. The remaining 65% is Tris buffer salts.
How should Product No. C2905 be reconstituted?
Reconstitute the product in a 0.01% bovine serum albumin aqueous solution. Subsequent dilutions can be made into a buffer containing 50 mM Tris, pH 8.0, with 60 mM sodium acetate and 0.02% bovine serum albumin. Solutions should be prepared fresh.
