Human IL2Rb (Interleukin 2 Receptor Beta) Microsample ELISA Kit

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 IL2Rb. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human IL2Rb. 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 IL2Rb, 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 IL2Rb in the samples is then determined by comparing the OD of the samples to the standard curve.Detection Range: 78.13-5000 pg/mL. Sensitivity: 30 pg/mL. Assay Type: Sandwich. Standard: 5000 pg/mL. Sample Type: sSerum, plasma, tissue homogenates and other biological fluids.. Assay duration: 3.5h. Protein Function: Receptor for interleukin-2. This beta subunit is involved in receptor mediated endocytosis and transduces the mitogenic signals of IL2. Probably in association with IL15RA, involved in the stimulation of neutrophil phagocytosis by IL15 (PubMed:15123770, PubMed:31040185) [The Uniprot Consortium]
