满江红鱼腥藻单克隆抗体的制备和应用研究

建立了40株分泌抗满江红鱼腥藻特异性单克隆抗体(McAb)的杂交瘤细胞株。 根据免疫荧光抗体试验,40个McAb分为8个类型。这8类McAb将采自世界名地的195个品种(系)满江红的体内鱼腥藻分为8个抗原群。 McAb对人工萍藻共生体和杂交满江红体内鱼腥藻的鉴定结果表明,人工萍藻共生体的鱼腥藻保持其在供体满江红叶腔中的抗原性,杂交满江红体内鱼腥藻保持其母本满江红体内鱼腥藻的抗原性,二者都不因蕨体遗传性状的改变而发生抗原结构变异。     

STUDY ON PREPARATION AND APPLICATION OF MONOCLONAL ANTIBODIES TO Anabaena azollae

Forty hybridoma cell lines secreting monoclonal antibodies against Anabaena azollae have been established by fusing SP_2/O myeloma cells with spleen cells from BALB/c mice immunized with purified antigen Anabaena azollae from different strains of azolla.According to the fluorescent antibody test, 40 McAbs were divided into 8 types. They may differentiate the Anabaena azollae in 195 azolla strains which are collected from different places in the world, into 8 antigenic groups.The identifying result of Anabaena azollae isolated from reconstituted azolla and sexual hybrid azolla showed that the Anabaena azollae in the reconstituted azolla retains its antigenicity from the donor azolla, and Anabacna azollae in hybrid azolla maintains its antigenicity from the female parent plant.
