Abstract— Porcine trypsin was inactivated by various methods (heat, autolysis, photodynamic action, ultraviolet light, and gamma-radiation) and the inactivated products were tested for their ability to precipitate porcine trypsin antiserum using the capillary fluid precipitin method. It was found that the chemical and structural modifications incurred with irradiation, sufficient to inactivate porcine trypsin, in contrast to heat and autolysis, did not interfere with those parts of the protein surface required for immunochemical reactivity. |
