ABSTRACT:
The present invention relates to a method for purifying bacterial cytolysins such as pneumococcal pneumolysin. A single chromatography step produces excellent purification of the cytolysin by binding soluble aggregated cytolysin to a hydrophobic interaction chromatography material in the presence of detergent and high salt.
