Type-I and type-III collagens were obtained by differential salt fractionation of neutral-salt-soluble collagen from rat skin. Their thermal stabilities were determined by u.v. difference spectroscopy. The ;melting' temperature (T(m)) in 5mm-acetic acid of type-III collagen was almost 2 degrees C above that of type-I collagen. Intramolecular covalent cross-linking had no effect on the thermal stability.
I型和III型胶原蛋白是通过对大鼠皮肤中中性盐溶性胶原蛋白进行分级盐析获得的。它们的热稳定性通过紫外差示光谱法测定。III型胶原蛋白在5mM乙酸中的“熔化”温度(T(m))比I型胶原蛋白高近2摄氏度。分子内共价交联对热稳定性没有影响。
