Cryptococcus neoformans cell and culture supernatant extracts were fractionated by ion exchange and gel filtration column chromatography. Various fractions were used to immunize mice, and to assess the release of migration inhibition factor, delayed type hypersensitivity, and protective immunity after challenge with C. neoformans. Results suggest that the C. neoformans fractions, which protect mice, contain a high molecular weight, predominantly carbohydrate antigen that can be distinguished from the capsular polysaccharide.
