摘要: 用可溶性日本血吸虫卵抗原(SEA)免疫小鼠制备单克隆抗体,获得5株特异的抗日本血吸虫卵单抗。免疫球蛋白亚类鉴定均为IgG_1。免疫印迹法结果表明其所识别的日本血吸虫卵抗原的分子量分别为200kDa、116kDa和22kDa。经两维免疫印迹法(2-Dimensional Western Blot),显示被单抗IE1识别的22kDa SEA等电点pI4.6—6之间至少有3个以上同晶型体(isomorphs)。放射免疫沉淀试验表明IE1可识别30kDa抗原。

Abstract: Monoclonal antibodies (McAbs) were generated from mice immunized with soluble egg antigen (SEA) of Schistosoma japonicum.Five of which were specific to SEA of S.ja-ponicum.The isotype of these McAbs was IgG1.Immunoblotting showed that the approximate molecule weight of the antigens recognized by the McAbs were 22kDa,116 kDa and 200 kDa respectively.At least 3 isomorphs of the 22 kDa antigen recognized by 1E1 were found at pI 4.6-6 with 2-D Western blot.Moreover,immunoprecipitation using 125I-labeled S.japonicum SEA demonstrated that only one band corresponding to 30 kDa was recognized by 1E1
