Description

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 receptor. IL-17A binds to a receptor that binds also to HVS13 (viral IL-17A) and to CTLA-8.

Applications Reported

For research use only, not for diagnostic or therapeutic use. Recombinant mouse IL-17A is biologically active. The intended use of the Recombinant Mouse IL-17A Single-Use ELISA RSG Standard is as a standard for mouse IL-17A Ready-SET-Go! ELISA and mouse IL-17A matched antibody pair ELISA. Typically the standard is run in a series of 7 doubling dilutions from the ‘top’ standard described below.

Instructions for use:
For Ready-SET-Go! ELISA Set (TMB substrate). Dilution: Add 5 ul of standard solution to 10 ml of assay diluent to prepare the top standard solution (500 pg/ml).
For matched antibody pair ELISA (ABTS or Super AquaBlue substrate). Dilution: Add 10 ul of standard solution to 10 ml of assay diluent to prepare the top standard solution (1000 pg/ml).

Note: These are single-use vials. Use one time and discard. Dilute as suggested above, not difficult-to-measure fractions of the suggested volumes (e.g., not 0.5 ul in 1.0 ml) or recovery may not be accurate. Use within 6 hours of dilution to top standard concentration.

Applications Tested

This cytokine standard has been calibrated, and subsequently tested by sandwich ELISA using the mouse IL-17A ELISA pair (eBio17CK15A5/eBio17B7).
