A study was made of the effect of gamma-irradiation of collalitin samples with doses of 25 and 50 kGy on proteolytic and enzyme activity with respect to denaturated collagen. The enzyme properties were found to change upon storage for periods of 6 and 12 months at 15 degrees C under unsterile conditions. No significant changes in the molecular mass of the collalitin samples were revealed by the method of gell-chromatography after irradiation and storage.
研究了剂量为25和50千戈瑞的γ射线辐照胶原蛋白样品对变性胶原蛋白的蛋白水解和酶活性的影响。发现在15摄氏度非无菌条件下储存6个月和12个月后，酶的性质发生了变化。辐照和储存后，通过凝胶色谱法未发现胶原蛋白样品分子量有显著变化。
