摘  要:
应用磺胺二甲基嘧啶(SM2)单克隆抗体(mAb)成功研制出SM2残留快速检测阻断ELISA试剂盒(SM2-Kit)。研究结果表明,SM2-Kit的标准曲线呈典型的S型,相关系数R2=0.9911,符合4参数logit曲线拟合,线性检测范围为0.625μg/L~80μg/L,灵敏度为0.9μg/L,半数抑制浓度(IC50)为5.82μg/L,检测限为1μg/L;饲料样、猪尿样的平均添加回收率分别为83.4%、89.5%,平均批内和批间变异系数均低于15%;SM2-Kit与磺胺甲基嘧啶的交叉反应率(CR%)为2.08%,与其它磺胺类药几乎没有反应性;基质对SM2-Kit的检测结果影响不大;试剂盒在4℃可保存6个月。

摘  要:
A blocking ELISA test kit for detection of Sulfanethazine(SM2) was developed with SM2 monoclonal antibodies(mAbs).The calibration curve of the SM2-Kit with standard SM2 inhibitor was typical sigmoid curve fitted to the four parameter logistic equation with the linear detection of 0.625 μg/L to 80.0 μg/L(R2=0.9911),the sensitivity of 0.9 μg/L,the IC50 of 5.82 μg/L and the detection limit of 1 μg/L.The recoveries of SM2 spiked in pig feed were 83.4 %,in pig urine were 89.5 %.The precision and accuracy of the assay as determined by inter-assay and intra-assay coefficient variation was both below 15 %.The SM2-Kit generally had 2.08 % cross-reactivity towards sulfamerazine and little or no cross-reactivity towards other sulfonamides.The dilution solution of SM2 had no effect on results of SM2-Kit.The validity of SM2-Kit in 4 ℃ was above six months.
