摘 要:用多肽固相合成仪合成人癌基因产物p185HER-2(即p185)胞内区的肽段,以之与沙门氏裸菌偶联制成免疫原,经脾内、腹腔、静脉途径免疫Balb/c小鼠,获得具有高抗体活性的脾细胞,后者与SP2/0融合,筛选出5株杂交瘤细胞系并对其分泌的单克隆抗体(McAb)特性进行了初步分析,ELISA检测腹水效价为10-4~10-6,用多肽和沙门氏裸菌分别进行中和试验,多肽抑制率在50%以上,而沙门氏裸菌则不能中和抗体反应。测定其中两株McAb亲和常数(Ka)分别为2.5×107M-1,5.0×108M-1。Synthetic polypeptide sequence corresponding to 15 amino acid residues of predicted antigenicity at the cterminus of a protein deduced from the human CerbB2 nucleotide sequence were sythesizedThe polypeptide combined with salmonella typhimurium was used as antigenIntrasplenic inoculation of the antigen was performed on Balb/c mice,then boosted intraperitoneally and intravenous injection was completed 3 days prior to fusion After fusion,selection and cloning procedures,5 hybridoma cell lines were successfully obtainedThe classes and subclasses,specificity and ascites titer of McAb were identifiedThe affinity constants of two hybridoma cell lines secreting McAb were 25×107M-1 and 50×108M-1 separetlyResults proved that the two McAb recognized the same epitope after epitope specificity analysis
