Recombinant Human IL-17E/IL-25 (Catalog # 1258-IL)

This antibody functions as an ELISA detection antibody when paired with Mouse Anti-Human IL‑17E/IL‑25 Monoclonal Antibody (Catalog # MAB1258).

This product is intended for assay development on various assay platforms requiring antibody pairs.

Measured by its ability to neutralize IL‑17E/IL‑25-induced CXCL1/GRO alpha secretion in the HT‑29 human colon adenocarcinoma cell line. The Neutralization Dose (ND50) is typically 0.04-0.24 ug/mL in the presence of 5 ng/ml Recombinant Human IL‑17E/IL‑25.

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.

Cell CXCL1/GRO Alpha Secretion Induced by IL‑17E/IL‑25 and Neutralization by Human IL‑17E/IL‑25 Antibody. Recombinant Human IL-17E/ IL-25 induces CXCL1/GRO alpha secretion in HT-29 human colon adenocarcinoma cell line in a dose-dependent manner (orange line), as measured by the Human CXCL1/GRO alpha Duoset (Catalog # DY275). Under these conditions, CXCL1/GRO alpha secretion elicited by IL-17E/IL-25 is neutralized (green line) by increasing concentrations of Goat Anti-Human IL-17E/IL-25 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1258). The ND50 is typically 0.04-0.24 ug/mL.

Background: IL-17E/IL-25

The Interleukin 17 (IL-17) family proteins, comprising six members (IL-17, IL-17B through IL-17F), are secreted, structurally related proteins that share a conserved cysteine-knot fold near the C-terminus, but have considerable sequence divergence at the N-terminus. With the exception of IL-17B, which exists as a non-covalently linked dimer, all IL-17 family members are disulfide-linked dimers. IL-17 family proteins are pro-inflammatory cytokines that induce local cytokine production and are involved in the regulation of immune functions (1, 2).

Human IL-17E cDNA encodes a 177 amino acid (aa) residues precursor protein with a putative 32 aa signal peptide (3). A second isoform of human IL-17E encoding a 161 aa precursor protein also exists (4). The two isoforms differ in their signal peptide sequences. Mature human IL-17E shares 76% aa sequence identity with mature mouse IL-17E. Human IL-17E also shares from 25% to 36% aa sequence identity with the other human IL-17 family members. IL-17E expression was detected at very low levels by PCR in various peripheral tissues including brain, kidney, lung, prostate, testis, adrenal gland spinal cord and trachea (3). IL-17E binds and activates IL‑17 B Receptor (IL-17B R) (alternatively known as IL-17 Rh1, IL-17E R, and EVI27) (3), which is expressed in kidney and liver, and at lower levels in brain, testis and other endocrine tissues. The expression of IL-17B R is up regulated under inflammatory conditions. Ligation of IL-17E to IL-17 RB induces activation of nuclear factor kappa-B and stimulates the production of the proinflamatory cytokine IL-8 (3). IL-17 has also been found to promote the expression of the prototypical Th2 genes (4, 5).

By Anonymous on 06/09/2020
Application: ELISA Sample Tested: Serum and Plasma Species: Human

We used this antibody in an in-house ELISA along with mAb (1258) and protein (1258-IL-025) to quantify IL-17E in human serum and plasma. This combination detected IL-17E in our samples efficiently.
