PeproTech IL-15 Polyclonal Antibody, PeproTech®, Invitrogen™

Description

AA Sequence of recombinant protein: MNWVNVISDL KKIEDLIQSM HIDATLYTES DVHPSCKVTA MKCFLLELQV ISLESGDASI HDTVENLIIL ANNSLSSNGN VTESGCKECE ELEEKNIKEF LQSFVHIVQM FINTS. Preparation: Produced from sera of rabbits immunized with highly pure Recombinant Human IL-15. Anti-Human IL-15-specific antibody was purified by affinity chromatography employing an immobilized Human IL-15 matrix. Sandwich ELISA: To detect Human IL-15 by sandwich ELISA (using 100 μL/well antibody solution) a concentration of 0.5-2.0 μg/mL of this antibody is required. This antigen affinity purified antibody, in conjunction with PeproTech Biotinylated Anti-Human IL-15 (500-P15Bt) as a detection antibody, allows the detection of at least 0.2-0.4 ng/well of Recombinant Human IL-15. Western Blot: To detect Human IL-15 by Western Blot analysis this antibody can be used at a concentration of 0.1-0.2 μg/mL. Used in conjunction with compatible secondary reagents the detection limit for Recombinant Human IL-15 is 1.5-3.0 ng/lane, under either reducing or non-reducing conditions.

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.
