摘要
用经草鱼生长激素(gcGH)免疫的BALB/c小鼠脾细胞与小鼠骨髓瘤细胞(Sp2/O-Ag14)融合,经3次克隆化培养和ELISA筛选,得到7株阳性杂交瘤细胞株,其中2株为强阳性。交叉试验表明,这些杂交瘤细胞株所分泌的单克隆抗体(McAb)同大鳞大马哈鱼生长激素(sGH)、大鳞大马哈鱼促性腺激素(sGTH)及牛生长激素(bGH)均不起反应。小鼠腹水McAbs滴度高达1:1280000。受体-gcGH-McAb夹心试验表明,McAb确与有活性的gcGH有特异反应。用间接ELISA方法可检测到浓度为0.125#g/ml的gcGH。
Monoclonal antibodies of hybridomas derived from fusing the mouse spleencytes immunized by gcGH with BALB / c mouse myeloma cells (Sp2 / 0-Agl4).Seven hybridomas cell lines were produced by indirect-ELISA screening and cloning for three times with limited dilution.In crossreaction test, these monoclonal antibodies didn't react with sGH, sGTH and bGH. Antibody liter of ascitic fluids was about 1 : 1280000 in indirect-ELISA. In receptor-gcGH-McAb sandwich-ELISA test, monoclonal antibodies reacted with biological-active gcGH. GcGH can be detected at the concentration of 0.125 /μg/ ml in indirect-ELISA.
