Rat IGFBP-4 (Insulin-Like Growth Factor Binding Protein 4) CLIA Kit

Type: Sandwich. Detection Range: 0.16~10ng/mL. Sensitivity: 0.09ng/mL. Tested Sample Types: Serum, Plasma, Cell supernatant. Test principle: This CLIA kit uses the Sandwich- CLIA principle. The micro CLIA plate provided in this kit has been pre-coated with an antibody specific to Rat IGFBP-4 . Standards or samples are added to the micro CLIA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat IGFBP-4 and Avidin-Horseradish Peroxidase(HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Rat IGFBP-4 , biotinylated detection antibody and Avidin-HRP conjugate will appear fluorescence. The Relative light unit(RLU) value is measured by the Chemiluminescence immunoassay analyzer. The RLU value is positively associated with the concentration of Rat IGFBP-4 . You can calculate the concentration of Rat IGFBP-4 in the samples by comparing the RLU value of the samples to the standard curve
