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 %.
