Abstract
A highly allergenic protein preparation apparently of 32,000 molecular weight has been isolated from the ragweed pollen extract by ammonium sulfate precipitation followed by chromatography on DEAE cellulose and on Sephadex. A second component of about 10,000 molecular weight was found to be also highly reactive in four out of thirty-two untreated hay fever patients. A cause for the gradual loss of the allergenic activity of ragweed pollen extract on storage is suggested.
