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.

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0.625 μg/L～80 μg/L，灵敏度为0.9 μg/L，半数抑制浓度(IC50)为5.82 μg/L，检测限为1 μg/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。
