Description

The eBio64CAP17 antibody reacts with human IL-17A; the antibody has been reported to cross react with Rhesus monkey IL-17A, as verified by intracellular staining experiments. The eBio64CAP17 antibody is a neutralizing antibody. Reactivity of the eBio64CAP17 antibody with other IL-17 family members has not been evaluated. 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-g and IL-4, have each been found to negatively regulate the generation of these Th-17 cells.

Applications Reported

For research use only, not for diagnostic or therapeutic use. 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 and recombinant human IL-17A (14-8179) as the standard. A suitable range of concentrations of this antibody for ELISA capture is 0.5 – 2.0 ug µg/ml. A standard curve consisting of doubling dilutions of the recombinant 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 30 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.
