Abstract
In cultures of spleen cells from tetanus toxoid-primed mice a soluble, nonspecific material appeared, which enhanced antibody response in vivo. The active material was purified by gel filtration on Sephadex-G-150 and by affinity chromatography on Con-A lectin. According to the immunological and physiochemical investigation the active material does not contain carbohydrate and its molecular weight is in the 100 000 dalton range.
