Quantikine®小鼠血清淀粉样蛋白A免疫测定法是一种4.5小时固相ELISA法,旨在测定细胞培养上清液、组织培养上清液、血清和血浆中的小鼠SAA。它包含大肠杆菌表达的重组小鼠SAA1和针对重组因子产生的抗体。这种免疫分析已被证明能准确定量重组小鼠SAA。使用天然小鼠SAA获得的结果显示,剂量反应曲线与使用Quantikine®小鼠试剂盒标准获得的标准曲线平行。这些结果表明,该试剂盒可用于测定天然小鼠SAA的相对质量值。
分析精密度(分析内的精密度)在一个平板上对三个已知浓度的样品进行20次测试,以评估分析内精密度
批间精密度(批间精密度)在20个不同的批间精密度中测试三个已知浓度的样品,以评估批间精密度。至少有三名技术人员使用两批成分进行分析
