title: [Staphylococcal toxic shock exotoxin (its isolation and characteristics)].
abstract: The method for obtaining the preparation of toxic shock exotoxin (TSE) has been developed. This method comprises the following operations: the sorption of the toxin from the culture fluid on Amberlite CG-50, elution, dialysis, gel chromatography in a column with biogel P-2, isoelectric focusing, and gel chromatography in a column with Sephadex G-75. TSE is a relatively thermostable protein with a molecular weight of 24,000. Its isoelectric point is 7.2. Monospecific antiserum to TSE with precipitating antibody titer equal to 1:16, identical to the reference serum (M. S. Bergdoll), has been prepared. This antiserum has shown no cross reactions with the homogeneous preparations of staphylococcal enterotoxins.
