Human Soluble Interleukin-2 Receptor Alpha Chain (IL-2sRa/CD25) ELISA Kit

• Catalog Number: orb776042
• Category: Assays and Kits
• Description: 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 Interleukin 2 Receptor Alpha(IL2Ra).
• Reactivity: Human
• Concentration: 1000 pg/mL
• Tested applications: ELISA
• Application notes: standard: 1000 pg/mL. Test principle: 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 IL-2sRa/CD25. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human IL-2sRa/CD25. 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 IL-2sRa/CD25, 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 IL-2sRa/CD25 in the samples is then determined by comparing the OD of the samples to the standard curve
