THE IMMUNIZING ANTIGEN OF THE PNEUMOCOCCUS : III. THE PURIFICATION OF THE WATER-SOLUBLE ANTIGEN.

W A Perlzweig1, C S Keefer.   

Abstract

Actively immunizing fractions of protein nature have been isolated from broth culture filtrates of Pneumococcus Type I by ultrafiltration, precipitation at a definite hydrion concentration, and the separation of a soluble picrate fraction. The method appears to be suitable for the initial purification of this antigen.
