title: Rapid purification of the main allergen of Lolium perenne by high-performance liquid chromatography.
abstract: The main allergen from rye grass (Lolium perenne) pollen was purified by size-exclusion high-performance liquid chromatography. The purified allergen had a molecular weight of 32,000 daltons and was significantly more active in solid phase radioimmunoassay than the whole extract. The highly purified antigen can be obtained very rapidly and with a recovery of 30%.
