  • Product overview

    Abcam’s IL-1a (Interleukin-1 alpha) Human in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of IL-1a in cell culture supernatants, buffered solutions, serum, plasma and other body fluids. This assay will recognize both natural and recombinant Human IL-1a.

    A monoclonal antibody specific for IL-1a has been coated to the wells of the microtiter strip plate provided. Samples, including standards of known IL-1a concentrations and unknown are pipetted into these wells. During incubation, binding of IL-1a to the capture antibodies is completed and then any excess unbound analyte is removed by washing. A biotinylated monoclonal antibody specific for IL-1a is then incubated. After washing, the enzyme (streptavidin-peroxydase) is added. After incubation and washing to remove all the unbound enzyme, a substrate solution which is acting on the bound enzyme is added to induce a coloured reaction product. The intensity of this coloured product is directly proportional to the concentration of IL-1 alpha present in the sample. 

    This kit will recognize both endogenous and recombinant Human IL-1a.

    Get higher sensitivity in only 90 minutes with Human IL-1a ELISA Kit (ab178008) from our SimpleStep ELISA® range.

  • RelevanceIL1 alpha is a member of the interleukin 1 cytokine family. It is a pleiotropic cytokine involved in various immune responses, inflammatory processes, and hematopoiesis. IL1 alpha is produced by monocytes and macrophages as a proprotein, which is proteolytically processed and released in response to cell injury, and thus induces apoptosis. This gene and eight other interleukin 1 family genes form a cytokine gene cluster on chromosome 2. It has been suggested that the polymorphism of these genes is associated with rheumatoid arthritis and Alzheimer's disease.
