Abstract
A purified allergen preparation, Timothy N, from timothy pollen (Phleum pratense) was characterized with respect to chemical properties in comparison with a commercially available crude extract, Timothy O, from the same pollen material. In Timothy N about 94% of the protein and 99% of both hexoses and pentoses were removed during the purification. Timothy N contains a limited number of proteins with molecular weights of about 15,000 and 30,000. A Timothy N solution of 0.010 mg/ml will have an allergenic activity of 1 HEP.Keywords
