Human IL-21 is a 4-helix-bundle-type fold cytokine with significant homology to IL-2, IL-4, and IL-15. IL-21 is produced most abundantly by activated CD4+ T cells, including Th17 lineage cells and natural killer T (NKT) cells, and has pleiotropic effects on both innate and adaptive immune responses. These actions include positive effects such as enhanced proliferation of NK cells and cytotoxic T cells that can destroy virally infected or cancerous cells and direct inhibitory effects on the antigen-presenting function of dendritic cells. It can also be proapoptotic for B cells and NK cells.
BioLegend’s LEGEND MAX™ Human IL-21 ELISA Kit is a sandwich Enzyme-Linked Immunosorbent Assay (ELISA), in which, a human IL-21 specific monoclonal antibody is pre-coated on a 96-well strip-well plate.
This Human IL-21 ELISA Kit is specifically designed for the accurate quantitation of human IL-21 from cell culture supernatant, serum, plasma, and other bodily fluids. It is ready-to-use, accurate, and sensitive.

Related FAQs
- In your LEGEND MAX™ ELISA Kits, there is a step that calls for washing the plates before adding sample. What is the purpose of this step?
-
We typically use a stabilizer for pre-coated plates. The additional washing step is designed to remove these components before you start the assay. If you do not perform the washing, the effect on assay performance is negligible.
- I have multiple LEGEND MAX™ ELISA kits that I want to run simultaneously. Can I use the same wash buffer for all the kits?
-
The wash buffer provided in all our LEGEND MAX™ kits is the same and the part numbers on the wash buffer bottles in these kits should be identical. For ELISA MAX™ Deluxe and ELISA MAX™ Standard Sets, we provide a recipe for the wash buffer on each kit’s technical data sheet. This recipe is the same for all ELISA MAX™ sets.
- For some of your ELISA kits, why do my serum samples require dilution with assay buffer?
-
In some cases, dilution with assay buffer is required to minimize the matrix difference between the samples and the standards to achieve better accuracy.
