IL-15 Rat anti-Mouse, Functional Grade, Clone: AIO.3, eBioscience
Rat Monoclonal Antibody
Manufacturer: Invitrogen 16715481
Description: The AIO.3 antibody reacts with mouse IL-15. This is a neutralizing antibody. Mouse IL-15 is a 14-15 kDa factor, previously known as IL-T. IL-15 is produced by a variety of cells and has a role in the T cell-mediated immune response and the central nervous system. IL-15 binds to the beta and gamma subunits of the IL-2 receptor; however, these two cytokines have distinct biological activities. IL-15 is a specific maturation factor for NK cells and mimics the BM microenvironment for NK cell development in vitro. It is reported that IL-15 delivers an anti-apoptotic and survival signal for NK, T, and B cells. Applications Reported: The AIO.3 antibody is reported for use in neutralization of mouse IL-15 bioactivity. Applications Tested: The Functional Grade Purified AIO.3 antibody has been tested by LAL assay to verify low endotoxin levels of < 0.01 ng/ug and in bioassay for neutralization of mouse IL-15 bioactivity. The AIO.3 antibody at less than or equal to 0.39 µg/mL has been found to inhibit by 50% the biological effects of 50 ng/mL mouse IL-15 (14-8151) in a CTLL2 proliferation assay. Detailed information and protocols about cytokine bioassays and in vitro cytokine neutralization using antibodies can be found in the BestProtocols® section. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Endotoxin: Less than 0.001 ng/ug antibody as determined by the LAL assay.Storage and handling: Use in a sterile environment. Filtration: 0.2 µm post-manufacturing filtered. Purity: Greater than 90%, as determined by SDS-PAGE. Endotoxin Level: Less than 0.001 ng/µg antibody, as determined by LAL assay. Aggregation: Less than 10%, as determined by HPLC. 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 ft.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.
