原始语种摘要: Abstract(#br)In this paper, a simple, rapid and high-throughput fluorescence polarization immunoassay (FPIA) based on polyclonal antibodies (PAb) is described for the determination of glycocholic acid (GCA) in human urine. Three fluorescein-labeled GCA (tracers) with different structures and spacer bridges were synthesized and purified by thin-layer chromatography (TLC). The structure effect of tracers on the assay was investigated and the sensitivity of best tracer in the optimized FPIA demonstrated an IC 50 value of 306 ng/mL. The working range of FPIA was 36 ∼ 2 600 ng/mL and the limit of detection (LOD) was 9 ng/mL. The developed FPIA was time-saving that could be completed within 10 min. Human urine samples spiked with GCA were analyzed by this method, followed by confirmation with...
