Anti Interleukin-32 (IL-32) pAb (Rabbit, Antiserum)

Human recombinant IL-32 does not exhibit similarities with known cytokine families, yet several properties are typical of a pro-inflammatory cytokine. It was discovered accidentally while studying the genes induced by IL-18 and was found to stimulate the production of various chemokines, pro-inflammatory cytokines including IL-1β, IL-6, IL-8, TNF-α and macrophage inflammatory protein-2 (MIP-2). Inflammation or infection with various pathogens including Mycobacterium tuberculosis, Epstein-Barr virus (EBV), human immunodeficiency virus (HIV) and influenza A virus have been reported to induce the expression of IL-32. The IL-32 gene is located on human chromosome 16 p13.3, which is organized into eight exons with six splice variants of the gene; these variants have been described as IL-32α, IL-32β, IL-32γ, IL-32δ, IL-32ε and IL-32ζ, of which, IL-32α is the most abundant transcript. Anti-tumor activity of NK cells is provoked by IL-12 and IL-18, both of which induce IL-32 production that stimulates TNF-α synthesis enhancing NK apoptotic activity. IL-32 was found in cytosol as well as in the nucleus. Park et al. reported that IL-32 enhances the anti-tumor activity specifically for NK-92 cells upon introduction of the death receptor and the activation of caspase-3 pathway in cancer cells. IL-32 has been reported to play a key role in the pathogenesis of various disorders, including infectious autoimmune and inflammatory diseases. Anti-IL-32 polyclonal antibody obtained from rabbit immunization with purified E. coli-derived recombinant human IL-32. This antibody can be used for the detection of IL-32 by immunoblotting and flow cytometry.
