抗粉尘螨主要变应原Der fⅡ单克隆抗体的制备与鉴定
Preparation and identification of monoclonal antibodies against Der f Ⅱ allergen
摘要
Abstract
In order to prepare monoclonal antibodies from mice against Der f II allergen from Dermatophagoid.es farinae and to characterize their properties, BALB/c mice were immunized with purified recombinant Der f II allergen protein, and the splenocytes of the immunized mice were fused with NS-1 myeloma cells by hybridoma technique. Indirect ELISA was used for screening the hybridoma cell lines which could secrete antibodies against Der f II. The McAbs against Der f fl allergen were purified using affinity chromatography on immobilized Protein G to identified their specificity, subtype, titers and cross-reactvity by ELISA and Western blotting. Five hybridoma cell lines secreting McAbs against Der f fl allergen were obtained, which were determined as IgG2a subtype and good ascites titers. The five McAbs against Der f II allergen all recognized recombinant Der f II allergen and native extract from Dermatophagoides farinae. Five monoclonal antibodies against Der f II allergen were prepared successfully, which will facilitate establishing detection method of Der Ⅱ allergen.关键词
