The CPL oligosaccharides always have a (J-(l - 4) linkage between the Gal-2 and Xyl residues and a 3-0 -> 3) linkage between Gal-3 and Gal-2, and HexA and Gal-3. The HexA is mostly 0-d-G1cA but it has been identified as a-L-IdoA in dermatan sulfate proteoglycan isolated from the CPL region of bovine aorta after reductive 3-elimination and subsequent digestion by chondroitinase ABC.102... 

In both the studies of Wight and Ross, and of Eisenstein and Kuettner, ruthenium red staining material was also found in the plasma membranes of endothelial cells and smooth muscle cells which was not removed with chondroitinase ABC and is therefore not chon-droitin sulfate or dermatan sulfate.

Chondroitinase ABC from Proteus vulgaris was purchased from Sigma Chemical Company. All inorganic chemicals were reagent grade. 

To check several of the immobilization methods, chondroitinase ABC (from Proteus vulgaris) was used as a control. A summary of the activity recoveries of immobilized heparinase and chondroitinase is listed in Table II. 

An examination of the effects of chronic and acute loss of glycosaminoglycans caused by Streptomyces hyaluronidase and chondroitinase ABC from the aqueous outflow pathway on the intraocular pressure and outflow facility in monkey eyes revealed that the intraocular pressure and outflow facility remained unchanged following acute and chronic intracameral chondroitinase ABC and hyaluronidase treatment in monkeys (18). However, the anterior chambers in dogs with normotensive and glaucomatous eyes treated with bovine testicular...

Effect of chondroitinase ABC. This enzyme (chondroitin ABC lyase, EC A.2.2.A.) also depolymerizes the hyaluronic acid backbone of aggregate. In addition, it can degrade chondroitin sulfate chains of monomer, but not its keratan sulfate chains. 

The effect on vlscoealstlc properties of concentrated solution (A% proteoglycan and lU chondroitinase ABC) was more or less similar to that with Streptomyces hyaluronidase treatment (Figure...
