摘要: 将石房蛤毒素(Saxitoxin,STX)与牛血清白蛋白(BSA)偶联构建完全抗原STX-BSA,免疫BALB/c小鼠,通过杂交瘤技术获得1株稳定分泌抗STX单克隆抗体的杂交瘤细胞株,单抗亚类为IgM。体内诱生法收集腹水单抗,间接ELISA方法测定抗体效价为1∶102400,抗体亲和常数为3.71×106 L/mol。

Abstract: Saxitoxin(STX)was conjugated to bovine serum albumin (BSA) as immune antigen. Inoculated mouse with STX-BSA, gained one hybridoma cell strains secreting monoclonal antibodies against STX stably. The subclass of the McAb was IgM. The titer of the McAb was 1∶102400 in ascites according to the indirect ELISA determination. The affinity constant was 3.71×106 L/mol.

Key words: Saxitoxin; antigen conjugate; monoclonal antibody(McAb); affinity constant
