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.

By studying the factors that affect the purities of products and recoveries of isoflavones, we got the optimum conditions for desorption: 70℃, eluting solvent sequence: water 3.0 BV, 75% ethanol 5.0 BV, flow-rate 2.5 mL·min~(-1). Under these conditions, the content of isoflavones in the product was 56.0% with the recovery of 89.3%. The content of isoflavones in the product was ten times larger than in the initial material.
