Abstract

With the combined use of skin tests, RAST and isoelectric focusing, a potency profile of a cocksfoot ((Dactylis glomerata) pollen extract was prepared. It was found that two fractions with pI 4.5 and 6.0 were the most allergenic, had the highest protein concentration and were also the most easily extracted. The importance of converting mean weal sizes into potency units when comparing the allergenicity of pollen fractions is emphasized.

摘要

通过联合使用皮肤试验、放射变应原吸附试验和等电聚焦技术，制备了鸭茅（鸭茅属）花粉提取物的效价图谱。结果发现，等电点为4.5和6.0的两个组分致敏性最强、蛋白质浓度最高，且最易提取。强调了在比较花粉组分的致敏性时将平均风团大小换算成效价单位的重要性。
