Product Information

KE00317 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The human IL-2RA ELISA kit is to be used to detect and quantify protein levels of endogenous human IL-2RA. The assay recognizes human IL-2RA. An antibody specific for human IL-2RA has been pre-coated onto the microwells. The human IL-2RA protein in samples is captured by the coated antibody after incubation. Following extensive washing, another horseradish peroxidase (HRP)-conjugated antibody specific for human IL-2RA is added to detect the captured human IL-2RA protein. For signal development, followed by Tetramethyl-benzidine (TMB) reagent. Solution containing sulfuric acid is used to stop color development and the color intensity which is proportional to the quantity of bound protein is measurable at 450 nm with the correction wavelength set at 630 nm.

Background Information

Proliferation of T lymphocytes is triggered by the interaction of IL-2 with its specific receptor following T lymphocyte activation. The receptor for IL-2 has three forms, generated by different combinations of three different proteins, the alpha chain (IL-2R alpha), the beta chain (IL-2R beta), and the gamma chain (IL-2R gamma). IL-2R alpha (also known as CD25) is a type I transmembrane protein present on activated T cells, activated B cells, some thymocytes, myeloid precursors, and oligodendrocytes. Soluble IL-2R alpha has been isolated and determined to result from extracellular proteolysis. Soluble IL-2R alpha has been found in the plasma of patients with certain hematologic malignancies. Elevated plasma or serum concentration of soluble IL-2R alpha has also been reported as a biomarker of immune activation.
