The eBioTC11-18H10.1 antibody is a neutralizing antibody. Interleukin-17A (IL-17A) 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. The cDNA encoding human IL-17A was isolated from a library of CD4+ T cells; the encoded protein exhibits 72 percent amino acid identity with HVS13 , an open reading frame from a T lymphotropic Herpesvirus saimiri, and 63 percent with mouse CTLA-8 (cytotoxic T-lymphocyte associated antigen-8). Human IL-17A exists as glycosylated 20-30 kD homodimers. High levels of IL-17A homodimer are produced by activated peripheral blood CD4+ T-cells. IL-17A enhances expression of the intracellular adhesion molecule-1 (ICAM-1) in human fibroblasts. 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 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-γ and IL-4, have each been found to negatively regulate the generation of these Th-17 cells. Applications ReportedFor research use only, not for diagnostic or therapeutic use. The eBioTC11-18H10.1 antibody has been reported for use as the capture antibody in mouse IL-17A ELISA and ELISPOT assay, for neutralization of IL-17A bioactivity, and for intracellular staining of IL-17A-producing cells. Applications TestedThe fluorochrome-conjugated eBioTC11-18H10.1 antibody has been tested by intracellular staining for flow cytometric analysis and can be used at less than or equal to 0.50 µg/million cells/100 ul staining volume. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. The Functional Grade Purified eBioTC11-18H10.1 antibody has been tested by LAL assay to verify low endotoxin and has been tested for neutralization of IL-17A bioactivity and for ELISPOT capture. The Affinity Purified eBioTC11-18H10.1 antibody has been tested as the capture antibody in a sandwich ELISA for measurement of mouse IL-17A protein levels, in combination with the biotinylated eBioTC11-8H4 antibody (13-7171) for detection and recombinant mouse IL-17A (14-8171) as the standard. A suitable range of concentrations of this antibody for ELISA capture is 0.5 – 2.0 µg/ml. A standard curve consisting of doubling dilutions of the recombinant standard over the range of 2000 pg/ml - 15 pg/ml should be included in each ELISA plate. References
