MBS917921 is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the interleukin 21 receptor (IL21R) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing IL21R. The ELISA analytical biochemical technique of the MBS917921 kit is based on IL21R antibody-IL21R antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect IL21R antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, IL21R. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).

For Sample For the quantitative determination of human interleukin-21 receptor (IL21R) concentrations in serum, plasma, tissue homogenates.

PRINCIPLE OF THE ASSAY This assay employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for IL21R has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any IL21R present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for IL21R is added to the wells. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of IL21R bound in the initial step. The color development is stopped and the intensity of the color is measured.

NCBI Summary for IL21R
The protein encoded by this gene is a cytokine receptor for interleukin 21 (IL21). It belongs to the type I cytokine receptors, and has been shown to form a heterodimeric receptor complex with the common gamma-chain, a receptor subunit also shared by the receptors for interleukin 2, 4, 7, 9, and 15. This receptor transduces the growth promoting signal of IL21, and is important for the proliferation and differentiation of T cells, B cells, and natural killer (NK) cells. The ligand binding of this receptor leads to the activation of multiple downstream signaling molecules, including JAK1, JAK3, STAT1, and STAT3. Knockout studies of a similar gene in mouse suggest a role for this gene in regulating immunoglobulin production. Three alternatively spliced transcript variants have been described.
