title: [Fractionation of Neisseria allergenic preparations by a gel chromatographic method on sepharose 4B].
abstract: The fraction composition of allergens obtained by different methods from the microbial mass of N. meningitidis, N. gonorrhoeae and N. perflava has been studied. Each method produced its characteristic number of fractions, irrespective of the Neisseria species used. Their molecular weights: more than 2,000,000 daltons, 160,000 daltons, 31,000 daltons and 14,000 daltons. All these fractions are biologically active.
