Detects canine IL-6 in ELISAs and Western blots. In sandwich ELISAs, less than 5% cross-reactivity with recombinant feline IL‑6 and recombinant porcine IL‑6 is observed, and less than 0.2% cross-reactivity with recombinant human IL-6, recombinant mouse IL‑6, recombinant rat IL‑6, recombinant cotton rat IL‑6, and recombinant equine IL‑6 is observed.

Recombinant Canine IL-6 Protein (Catalog #
Measured by its ability to neutralize IL‑6-induced proliferation in the T1184.108.40.206 mouse plasmacytoma cell line. The Neutralization Dose (ND50) is typically 0.4-2.0 µg/mL in the presence of 50 ng/mL Recombinant Canine IL‑6.
Please Note: Optimal dilutions should be determined by each laboratory for each application.

Cell Proliferation Induced by IL‑6 and Neutralization by Canine IL‑6 Antibody.
Recombinant Canine IL‑6 (Catalog # 1609-CL) stimulates proliferation in the T1220.127.116.11 mouse plasmacytoma cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Canine IL‑6 (50 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Canine IL‑6 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1609). The ND50 is typically 0.4-2.0 µg/mL.
Detection of IL‑6 in CLL‑1390 Canine Cell Line by Flow Cytometry.
CLL‑1390 canine leukocytic round cell neoplasia cell line was stained with Goat Anti-Canine IL‑6 Antigen Affinity‑purified Polyclonal Antibody (Catalog # AF1609, filled histogram) or control antibody (Catalog # AB-108-C, open histogram), followed by Allophycocyanin-conjugated Anti-Goat IgG Secondary Antibody (Catalog # F0108). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.
IL‑6 in Canine PBMCs.
IL‑6 was detected in immersion fixed canine peripheral blood mononuclear cells (PBMCs) stimulated with PHA using Goat Anti-Canine IL‑6 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1609) at 15 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Interleukin 6 (IL-6) is a pleiotropic alpha -helical cytokine that plays important roles in acute phase reactions, inflammation, hematopoiesis, bone metabolism, and cancer progression. IL-6 activity is central to the transition from acute inflammation to either acquired immunity or chronic inflammatory disease. It is secreted by multiple cell types as a 22-28 kDa phosphorylated and variably glycosylated molecule (1-4). Mature canine IL-6 is 187 amino acids (aa) in length and shares 76%, 59%, 38%, and 40% aa sequence identity with feline, human, mouse, and rat IL-6, respectively (5). IL-6 induces signaling through a cell surface heterodimeric receptor complex composed of a ligand binding subunit (IL-6 R) and a signal transducing subunit (gp130). IL-6 binds to IL-6 R, triggering IL-6 R association with gp130 and gp130 dimerization (6). gp130 is also a component of the receptors for CLC, CNTF, CT-1, IL-11, IL-27, LIF, and OSM (7). Soluble forms of IL-6 R are generated by both alternate splicing and proteolytic cleavage (3). In a mechanism known as trans-signaling, complexes of soluble IL-6 and IL-6 R elicit responses from gp130-expressing cells that lack cell surface IL-6 R (3). Trans-signaling enables a wider range of cell types to respond to IL-6, as the expression of gp130 is ubiquitous while that of IL-6 R is predominantly restricted to hepatocytes, leukocytes, and lymphocytes (3). Soluble splice forms of gp130 block trans-signaling from IL-6/IL-6 R but not from other cytokines that utilize gp130 as a coreceptor (4, 8).
