Detects human IL‑17 RA/IL‑17 R in direct ELISAs and Western blots. In direct ELISAs and Western blots, less than 1% cross-reactivity with recombinant mouse IL‑17 RA/IL‑17 R is observed.
Polyclonal Goat IgG
Mouse myeloma cell line NS0-derived recombinant human IL‑17 RA/IL‑17 R Leu33-Trp320 Accession # Q96F46
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
<0.10 EU per 1 μg of the antibody by the LAL method.
2.5 µg/106 cells
K562 human chronic myelogenous leukemia cell line
Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.
Measured by its ability to neutralize IL‑17-induced IL‑6 secretion in normal human dermal fibroblasts. Yao, Z. et al. (1995) Immunity 3:811. The Neutralization Dose (ND50) is typically 0.1-0.5 µg/mL in the presence of 25 ng/mL Recombinant Human IL‑17.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Detection of Human IL‑17 RA/IL‑17 R by Western Blot. Western blot shows lysates of K562 human chronic myelogenous leukemia cell line. PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human IL‑17 RA/IL‑17 R Antigen Affinity-purified Polyclonal Antibody (Catalog # AF177) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for IL‑17 RA/IL‑17 R at approximately 160 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
IL‑6 secretion Induced by IL‑17 and Neutralization by Human IL‑17 RA/IL‑17 R Antibody. Recombinant Human IL‑17 (Catalog # 317-ILB) stimulates IL‑6 secretion in normal human dermal fibroblasts in a dose-dependent manner (orange line), as measured by the Human IL‑6 Quantikine ELISA Kit (Catalog # D6050). IL‑6 secretion elicited by Recombinant Human IL‑17 (25 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human IL‑17 RA/IL‑17 R Antigen Affinity-purified Polyclonal Antibody (Catalog # AF177). The ND50 is typically 0.1-0.5 µg/mL.

Background: IL-17 RA/IL-17 R
Interleukin 17 (also known as CTLA-8) is a T cell-expressed pleotropic cytokine. IL-17 binds to IL-17 receptor (IL-17 R) which shares no homology with any known family of receptors. While the expression of IL-17 is restricted to activated T cells, the IL-17 R mRNA exhibits a broad tissue distribution, and has been detected in virtually all cells and tissues tested. The human IL‑17 R gene was localized to chromosome 22. Human IL-17 R is an 866 amino acid (aa) type I membrane glycoprotein with a 293 aa extracellular domain, a 21 aa carboxy-proximal transmembrane domain, and a 525 aa cytoplasmic tail. The aa sequence of human IL‑17 R is 69% identical to the mouse IL‑17 R. The signaling events of IL-17 includes activation of NF-kappa B and JNK, and require TNF receptor-associated factors 6 (TRAF6) in the signaling pathway.
