Isolation and characterization of proteoglycans from bovine aorta.

Proteoglyeans from bovine aorta were extracted by 0.15 M NaCl and by digestion with collagenase and with elastase. The nonspecific protease activity of elastase was inhibited by soybean trypsin inhibitor. Glycosaminoglycans (GAG) of the proteoglycans were isolated, characterized, and quantitated. About 50% of the tissue chondroitin 4and B-sulfates, 75% of… CONTINUE READING
