Test Principale: This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human CR2/CD21. Samples (or Standards) are added to the micro ELISA 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 blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 ± 2 nm. The OD value is proportional to the concentration of Human CR2/CD21. You can calculate the concentration of Human CR2/CD21 in the samples by comparing the OD of the samples to the standard curve.

Specifivity: This kit recognizes Human CR2/CD21 in samples. No significant cross-reactivity or interference between Human CR2/CD21 and analogues was observed.

Research Areas: Cancer, Immunology

Storage: An unopened kit can be stored at 2-8℃ for 1 month. If the kit is not supposed to be used within 1 month, store the items separately according to the storage table in the manual once the kit is received.
