Human CR2/CD21 (Complement Receptor 2) CLIA Kit

Type: Sandwich. Detection Range: 62.5~4000pg/mL. Sensitivity: 37.5pg/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 Human CR2/CD21 . Standards or samples are added to the micro CLIA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human CR2/CD21 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 Human CR2/CD21 , 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 Human CR2/CD21 . You can calculate the concentration of Human CR2/CD21 in the samples by comparing the RLU value of the samples to the standard curve
