Detects human IL‑36 gamma /IL‑1F9 in direct ELISAs and Western blots. In direct ELISAs, approximately 15% cross-reactivity with recombinant human (rh) IL-36 alpha is observed, approximately 5% cross-reactivity with rhIL-37 is observed, and less than 1% cross-reactivity with rhIL-1 alpha, rhIL-1 beta, rhIL‑36Ra, and rhIL‑36 beta is observed.
Polyclonal Goat IgG
E. coli-derived recombinant human IL‑36 gamma /IL‑1F9 (R&D Systems, Catalog # 2320-IL) Met1-Asp169 Accession # Q9NZH8
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.
Blockade of Receptor-ligand Interaction
In a functional ELISA, 0.7-2.8 µg/mL of this antibody will block 50% of the binding of 5 μg/mL of Recombinant Human IL-1 Rrp2/IL-1 R6 Fc Chimera (Catalog # 872-RP) to immobilized Recombinant Human IL‑36 gamma /IL‑1F9 (Catalog # 2320-IL) coated at 1 µg/mL (100 µL/well). At 10 μg/mL, this antibody will block >90% of the binding.
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‑36 gamma /IL‑1F9 by Western Blot. Western blot shows lysates of A431 human epithelial carcinoma cell line untreated (-) or treated (+) with 20 ng/mL Recombinant Human IFN‑ gamma (Catalog # 285‑IF) and 20 ng/mL Recombinant Human TNF‑ alpha (Catalog # 210‑TA) for 6 hours. PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human IL‑36 gamma /IL‑1F9 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2320) followed by HRP‑conjugated Anti‑Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for IL‑36 gamma /IL‑1F9 at approximately 18 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: IL-36 gamma/IL-1F9
Human interleukin 1 family member #9 [IL-1F9; also named Interleukin-36 gamma, IL36G, IL-1 epsilon (epsilon) and IL-1H1] is a member of the IL-1 family, which includes IL-1 beta, IL-1 alpha, IL-1ra, IL-18 and IL-1F5 through F10 (1‑4). All family members show a 12 beta -strand, beta -trefoil configuration, and are believed to have arisen from a common ancestral gene that has undergone multiple duplications (4). IL-1F9 is synthesized as a 19 kDa, 169 amino acid (aa) protein that contains no signal sequence, no prosegment and no potential N-linked glycosylation site (1, 2, 5). The molecule is secreted when transfected into 293-T cells (5). Human to mouse, IL-1F9 has 53% aa sequence identity. Within the family, IL-1F9 shares 30%, 23%, 33%, 57%, 35%, 45%, and 32% aa sequence identity with IL-1 ra, IL-1 beta, IL-1F5, F6, F7, F8, and F10, respectively. Cells reported to express IL-1F9 include Langerhans cells, keratinocytes/stratified squamous epithelium, plus Chief cells and Parietal cells of the stomach (4, 5). The receptor for IL‑1F9 is reported to be a combination of IL-1 Rrp2 and IL-1 RAcP (6). Recombinant IL-1F9, along with IL-1F8 and IL-1F6, has been shown to activate the pathway involving NF-kappa B and MAPK in an IL-1 Rrp2 dependent manner.
