Anti-Interleukin 17 (IL-17, CTLA8, IL-17A, Interleukin-17A precursor, Cytotoxic T-lymphocyte-associa

Interleukin 17 (also known as CTLA-8) is a T cell-expressed pleiotropic cytokine that exhibits a high degree of homology to a protein encoded by the ORF13 gene of herpes virus Saimiri. cDNA clones encoding IL-17 have been isolated from activated rat, mouse and human T cells. Human IL-17 cDNA encodes a 155 amino acid (aa) residue precursor protein with a 19 amino acid residue signal peptide that is cleaved to yield the 136 aa residue mature IL-17 containing one potential N-linked glycosylation site. Both recombinant and natural IL-17 have been shown to exist as disulfide linked homodimers. At the amino acid level, hIL-17 shows 72% and 63% sequence identity with herpes virus and rat IL-17, respectively. An IL-17 specific mouse cell surface receptor (IL-17 R) has recently been cloned. While the expression of IL-17 mRNA is restricted to activated T cells, the expression of mIL-17 R mRNA has been detected in virtually all cells and tissues tested. IL-17 exhibits multiple biological activities on a variety of cells including the induction of IL-6 and IL-8 production in fibroblasts, the enhancement of surface expression of ICAM-1 in fibroblasts, activation of NF-kB and co-stimulation of T cell proliferation. The non-glycosylated, E. coli-expressed rhIL-17 has been shown to be active on human as well as mouse cell lines. Applications: Suitable for use in Flow Cytometry. Other applications not tested. Recommended Dilutions: Flow Cytometry: Neat. 10ul labels up to1x10e6 cells., Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C before opening. DO NOT FREEZE! Stable at 4°C as an undiluted liquid. Dilute only pror to immediate use. Freezing Allophycocyanin conjugates will result in a substantial loss of activity.
