原始语种摘要: Abstract(#br)Trace concentrations of cholyglycine acid (CG) are useful to reflect the damage degree in liver cells, and useful in the diagnosis and prognosis of liver diseases. Therefore, developing an effective strategy to detect the concentration of CG is of great importance. A homogeneous fluorescence polarization immunoassay (FPIA) was developed for determination of CG concentrations. The effects of tracer concentration, antibody dilution and incubation time on FPIA performance were studied. The FPIA was used to detect CG in sera from 522 patients with liver diseases and 449 healthy controls. The results were compared with those obtained through enzyme multiplied immunoassay technique (EMIT). The FPIA showed a detection limit of 50.9ng/mL for CG and the...
