title: Polymerization of individual species of tree pollen allergens.
abstract: This report describes the preparation of individual tree pollen allergen polymers in contrast to our previous description of the polymerization of a mixture of tree pollens.. These individual polymers may be used for immunotherapy as indicated by the IgE-mediated reactivity of each patient. A modified chromatographic fractionation process was used which results in tree polymers with skin reactivity 1,000- to 10,000-fold less from monomers and with a defined lower molecular weight limit. The modified preparative methodology results in polymer preparations as safe but with greater ease of production than polymers prepared with previous methodologies.
