DescriptionMouse, rat, and human IL-17A can induce IL-6 secretion in mouse stromal cells, indicating that all homologs can recognize the mouse IL-17A receptor. IL-23-dependent, IL-17A-producing CD4+ T cells (Th-17 cells) have been identified as a unique subset of Th cells that develops along a pathway that is distinct from the Th1- and Th2- cell differentiation pathways. The hallmark effector molecules of Th1 and Th2 cells, e.g., IFN-g and IL-4, have each been found to negatively regulate the generation of these Th-17 cells. Additionally, activated human CD4+ T cells have been found to produce the IL-17A/F heterodimer, as well as the corresponding homodimers. In comparing the relative potency of IL-17A, IL-17F, and IL-17A/F, all three were found to induce GRO-a secretion; IL-17A was most potent, followed by IL-17A/F heterodimer, then IL-17F (100fold lower than IL-17A). eBio64CAP17 can be used to detect IL-17 heterodimers by immunoprecipitation followed by immunoblot withH17F10A7 anti-IL17F monoclonal antibody. The eBio64CAP17 has been shown to react to rhesus and marmoset primates. Applications Reported: The eBio64CAP17 antibody has been reported for use as the capture antibody in a human IL-17A ELISA and ELISPOT assay, for neutralization of IL-17A bioactivity, and for intracellular staining of IL-17A-producing cells. Applications Tested: The Affinity Purified eBio64CAP17 antibody has been tested as the capture antibody in a sandwich ELISA for measurement of human IL-17A protein levels, in combination with the biotinylated eBio64DEC17 antibody (13-7179) for detection andrecombit human IL-17A (14-8179) as the standard. A suitable range of concentrations of this antibody for ELISA capture is 0.5 - 2.0 µg µg/mL. A standard curve consisting of doubling dilutions of the recombit standard over the range of 1000 pg/mL - 8 pg/mL should be included in each ELISA plate. The Functional Grade Purified eBio64CAP17 antibody has been tested by LAL assay to verify lowest endotoxin levels and has been tested for neutralization of IL-17Abioactivity and for ELISPOT capture. For in vitro neutralization, the eBio64CAP17 antibody at less than or equal to 63 ng/mL has been found to neutralize by 50% the biological effect of 5 ng/mL human IL-17A, based on induction of IL-6 secretion by the NHDF cell line. 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. Interleukin-17A (IL-17A, CTLA-8) is a CD4+ T cell-derived cytokine that promotes inflammatory responses in cell lines and is elevated in rheumatoid arthritis, asthma, multiple sclerosis, psoriasis, and transplant rejection. IL-17A is a 32 kDa long, disulfide-linked homodimer consisting of 136 amino acids that is a member of a six-species family of proteins (IL-17A-17F) and signals through the IL-17 receptor (IL-17R/CDw217). High levels of IL-17A homodimer are produced by activated peripheral blood CD4+ T-cells, and IL-17A also enhances expression of the intracellular adhesion molecule-1 (ICAM-1) in human fibroblasts. In particular, human IL-17A also stimulates epithelial, endothelial, or fibroblastic cells to secrete IL-6, IL-8, G-CSF, and PGE2. In the presence of human IL-17A, fibroblasts can sustain the proliferation of CD34+ hematopoietic progenitors and induce maturation into neutrophils. Mouse, rat, and human IL-17A can induce IL-6 secretion in mouse stromal cells, indicating that all homologs can recognize the mouse receptor. IL-17A regulates the activities of NF-kappa B and mitogen-activated protein kinases, stimulates the expression of IL-6 and cyclooxygenase-2 (PTGS2/COX-2), and enhances the production of nitric oxide (NO).
