About This Kit
Kit Overview
The Human IL-15 ELISA kit enables the quantification of Human IL-15 in various biological samples, including human serum, plasma, buffered solutions, and cell culture medium. This assay is specifically designed to exclusively detect both natural and recombinant forms of Human IL-15.
Principle of the assay
The Human IL-15 solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) follows a unique approach to measure the amount of the target molecule. It utilizes a matched pair of antibodies to capture the target and form a sandwich complex. The first antibody is pre-coated on the microplate wells, where samples, standards, or controls are added and bind to the immobilized antibody. The second antibody, acting as the detector, is then introduced, followed by the addition of a substrate solution that generates a measurable signal upon interaction with the enzyme-antibody-target complex. The intensity of this signal directly correlates to the concentration of the target present in the original specimen.

Target information
IL-15 (Interleukin 15 ) is a cytokine that regulates T and natural killer cell activation and proliferation. IL-15 and IL-2 share many biological activities as both have been found to bind common hematopoietin receptor subunits, and may compete for the same receptor, and thus negatively regulate each other's activity. The number of CD8+ memory cells is shown to be controlled by a balance between IL-15 and IL-2. IL-15 induces the activation of JAK kinases, as well as the phosphorylation and activation of transcription activators STAT3, STAT5, and STAT6. In mouse, studies suggest that IL-15 may increase the expression of apoptosis inhibitor Bcl-xL, possibly through the transcription activation activity of STAT6, and thus prevent apoptosis. IL-15 plays an important role in the growth and differentiation of T and B lymphocytes, natural killer cells, macrophages, and monocytes as well as activation of a number of important intracellular signaling molecules. As such, IL-15 could be essential for the immune responses, allograft rejection, and the pathogenesis of autoimmune diseases. Further, IL-15 is a widely expressed pro-inflammatory cytokine and has been shown to play a role in several inflammatory disorders, including rheumatoid arthritis, psoriasis and pulmonary inflammatory diseases. Emerging data suggest that IL-15 may serve as a good therapeutic target, as there appears to be a beneficial effect of IL-15 neutralization in models of psoriasis and diabetes.
