title: [Biochemical and immunochemical study of antigen preparations of Rickettsia prowazekii].
abstract: The biochemical and immunochemical study of the qualitative composition of R. prowazekii antigenic preparations, isolated and purified by different methods, indicates that these preparations contain high-molecular polypeptide 3 (133600 D), morphologically linked with the cell membrane of R. prowazekii. The method of adsorption chromatography on calcium phosphate permits obtaining specific rickettsial antigens with a greater degree of purification from ballast admixtures than the methods of acid precipitation and gel filtration on Sephadex G-200.
