[Identification of proteases of staphylococci by means of an antitrypsin precipitating serum].
Specific antitrypsin precipitating sera obtained by intraconjunctival immunization of rabbits with crystalline trypsin was used to reveal in the supernant of staphylococcal cultures protease having antigenic character common with that of trypsin. This is confirmed by the trypsin accumulation in the process of staphylococcus cultivation, by the inhibition of the proteolytic activity of the antitrypsin precipitating sera and by the production of protein-precipitate as a result of incubation of the supernant with the antitrypsin precipitating sera.
