Ribonucleic acid-protein purified from Salmonella typhi involved in experimental immunity.

Abstract

An immunogenic complex was obtained from Salmonella typhi by the bacterial acetone powder method. This complex induced in mice a high degree of protection against a challenge with the virulent Salmonella. This immunogenic complex was fractionated at least into 19 fractions when chromatographied on a DEAE-cellulose column. By SDS-polyacrylamide gel… (More)
