摘要
研制了一种用于检测土壤中克百威残留量的直接竞争ELISA(酶联免疫分析技术)试剂盒,研究结果表明:该试剂盒的最低检测限为0.01mg/L,线性检测范围为0.01～10mg/L,4种水样的批内、批间、整体变异系数均低于7.72%,回收率的范围在93.97%～97.92%。试剂盒在4℃或-20℃下至少可保存6个月以上。
A ELISA kit based on polyclonal antibody was developed to detect the residue of carbofuran in soil. Linear detection of the kits covered a range from 0.01 mg/L to 10.00 mg/L. The mean within- assay?between-assay and total-assay variability were less than 7.72%. The recoveries of carbofuran added to sample ranged from 93.974% to 97.92%. The validity of kit in 4 ℃ or -20 ℃ was both above six months.
