title: [Allergenic activity of some kinds of plant pollen].
abstract: Allergenic active fractions of ragweed, wormwood, goosefoot and sunflower pollen with a molecular weight of 37 000, 19 000, 35 000 and 14 000, respectively, were isolated by chromatography on Sephadex. All studied allergens had similar properties: affinity to Sephadex which was more pronounced to Sephadex G-75 than to G-100; absorbing components had no activity; allergenic and antigenic activities were determined only in fractions eluted in the bed volume of the column. Affinity of the allergans to Sephadex did not depend on the eluent type, but decreased in potentiation of the buffer ionic strength.
