[Collagen gels, chondroitin-4-sulfate. Proteolytic stability]. / Kollagenovye geli, khondroitin-4-sul'fat, ustoichivost' k proteolizu.

Differential scanning microcalorimetry and polarized thermomicroscopic methods were used for studying of collagen type I and chondroitin-4-sulfate complexes. It was shown that fast heating till 37 degrees C lead to collagen gel formation, which is stable for collagenase action.
