【摘要】 <正> 在单克隆抗体的制备中,亲和力和特异性的测定是非常重要的。实验证明单抗的特异性不是绝对的,我们也发现在免疫酶组化染色过程中,当单抗浓度达到一定水平时会出现交叉反应,即抗3型(或7型)腺病毒单抗与7型(或3型)腺病毒出现反应。因此有必要测定单抗特异性,以便筛选高特异性的单抗。更多还原

【Abstract】 To measure the relative affinity and type Specificity of neutralizing monoclonal antibodies against the hexon antigen of adenovirus type 7,a simple ELISA double antibody binding system has been developed.By this method,ralative affinity of nine MAbs was estimated from the antibody concentrations at approximately 50% of plateau binding and were ranked.The theoretical basis for this method was discussed. Hybridomas secreting antibodies of desired affinity can be selected at an early stage after fussion by measuring relative affinity of hybridomas supernatants.The type specificity was judged by the difference between end-point concentration against adeno- virus type 7 and type 3.And the relation between affinity and specificity of MAbs was discussed.更多还原
