Description

The Human Interleukin 15 (IL-15) Uncoated ELISA Kit contains pre-matched antibody pairs, plates and reagents for performing quantitative enzyme linked immunosorbent assays (ELISA) to detect and quantify protein levels of human IL-15. Wash Buffer and Stop Solution are needed to complete the ELISA reaction and are sold separately. Principle of the method ELISAs are designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody is coated to the bottom of the wells of a microplate, which is an overnight process. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. A sandwich is formed by the addition of the second (detector) antibody, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen.

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.
