摘  要:
利用沙丁胺醇半琥珀酸与异硫氢酸荧光素己二胺衍生物反应合成荧光示踪物SAL-HDF,通过优化示踪物和抗体的最适工作质量浓度,建立一种检测沙丁胺醇的荧光偏振免疫分析方法。结果表明:该方法的检出限为72.36ng/mL,半抑制质量浓度(IC50)为975.18ng/mL,检测范围(IC20~IC80)为178.08~4871.15ng/mL。

摘  要:
A fluorescence polarization immunoassay(FPIA) was presented to detect salbutamol.Fluorescence-labeled salbutamol tracer(SAL-HDF) was synthesized via the reaction of salbutamol-succinate(SAL) with fluoresceinthiocarbamyl ethylendiamine(HDF).Several parameters that might affect the performance of FPIA such as SAL-HDF and anti-salbutamol antibody concentration were optimized.Under the optimum conditions,the limit of detection was 72.36 ng/mL,the IC50 was 975.18 ng/mL,and the linear range of the developed FPIA was 178.08–4871.15 ng/mL.This method can provide a useful reference to develop a salbutamol FPIA test kit.
