- Chondroitin sulfate (CS), a linear polysaccharide, is a major component of the cartilage matrix. Although CS plays various roles in several biological and pathological processes, most details regarding its metabolism are still poorly understood. Some CS-degrading enzymes have been identified in mammals, but their expression patterns and localizations remain unclear. Here we present a simple zymography procedure to detect CS-degrading enzymes using salmon nasal cartilage proteoglycans as substrates. This method should be useful to explore CS-degrading enzymes.
