Human IL21(Interleukin 21) ELISA Kit is a research-use ELISA kit from ELK Biotechnology for measuring IL21 in Serum, Plasma, 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.
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 IL21. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human IL21. 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 IL21, 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 IL21 in the samples is then determined by comparing the OD of the samples to the standard curve.
Alternative names include IL-21;Za11.

IL21 identifies interleukin 21 in Homo sapiens (Human). This target record connects NCBI Gene 59067, UniProtKB Q9HBE4 and related ABMIUM catalogue products.
Biological function: IL21 is an immunoregulatory cytokine produced mainly by activated CD4-positive T-cell subsets and natural killer T cells. Through its receptor complex it influences proliferation, differentiation and effector functions across B cells, T cells, natural killer cells and other immune populations.
