[The effect of gamma radiation on the enzyme activity of collalitin during storage]

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.
