Human CD8b(Cluster Of Differentiation 8b) ELISA Kit

Human CD8b(Cluster Of Differentiation 8b) ELISA Kit is a research-use ELISA kit from ELK Biotechnology for measuring CD8b in Tissue homogenates, Cell lysates, Cell culture supernatant, Other biological fluids samples from Human. Use the listed assay range, sample guidance and protocol documents to assess suitability for the intended study.

Test principle

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human CD8b. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human CD8b. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human CD8b, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human CD8b in the samples is then determined by comparing the OD of the samples to the standard curve.

Target background

Alternative names include CD8B1; CD8 Antigen,Beta Polypeptide 1; T-cell surface glycoprotein CD8 beta chain.
