| Rat anti Human Interleukin-2 antibody, clone MQ1-17H12recognizes human interleukin-2 (IL-2), also known as T-cell growth factor or Aldesleukin. IL-2 is a 153 amino acid secreted cytokine produced by T-cells following antigenic or mitogenic stimulation. It plays a crucial role in T-cell proliferation and immune regulation.Rat anti Human Interleukin-2 antibody, clone MQ1-17H12 has been sucessfully used for the detection and measurement of native and recombinant human IL-2 using flow cytometry and ELISA where it ascts as the capture reagent in a very sensitive assay for IL-2 determination in human samples. IL-2 is used extensively for the treatment of patients with metastatic melanoma (Atkinset al.1999) and renal cancer with reproducible benificial effects (Rosenberg 2014). Monitoring of IL-2 levels in such patients is required for optimization of treatment regimens (Lotzeet al.1986). Rat anti Human Interleukin-2 antibody, clone MQ1-17H12 is also useful for evaluating levels of IL-2 in patients with autoimmune conditions including lupus erythematosus and rheumatoid arthritis where there may be an impaired ability to produce IL-2 (Talalet al.1983). |

| This product has been reported to work in the following applications. This information is derived from testing within our laboratories, peer-reviewed publications or personal communications fromthe originators. Please refer to references indicated for further information. For general protocol recommendations, please visit theantibody protocolspage.1Membrane permeabilization is required for this application. Bio-Rad recommend the use of Leucoperm™(Product CodeBUF09) for this purpose.Where this antibody has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. It is recommended that the user titrates the antibody for use in their own system using appropriate negative/positive controls.Flow CytometryUse 10ul of the suggested working dilution to label 1x106cells in 100ul. |
