STUDIES ON TUBERCULIN FRACTIONS I. CHANGES IN THE AMOUNT OF TUBERCULIN FRACTIONS CAUSED BY HEATING

From unheated and heated culture filtrates of human tubercle bacilli and BCG grown on synthetic media, three different proteins and two different polysaccharides were fractionated according to their solubility and precipitability by alcohol precipitation at low temperature. The fractions obtained fr...

Summary:From unheated and heated culture filtrates of human tubercle bacilli and BCG grown on synthetic media, three different proteins and two different polysaccharides were fractionated according to their solubility and precipitability by alcohol precipitation at low temperature. The fractions obtained from unheated filtrates were designated by Seibert as protein A, B and C and polysaccharides and II; and those obtained from heated filtrates were provisionally named by the present author as protein hA, hB and hC and polysaccharides hI and hII.
