Purification of a factor which provides a costimulatory signal for gamma interferon production.

abstract：:The quantity of membrane-bound and extracellular exotoxin A in four strains of Pseudomonas aeruginosa was investigated. In strain PA-103, which is the prototype strain used for toxin production, all of the toxin was released into the growth medium and little toxin remained with the cell envelope. In a virulent strain ...
