Interleukin-5 (IL-5) is a 40‑45 kDa secreted disulfide-linked homodimeric glycoprotein that plays an important role in the differentiation, growth, and function of eosinophils. It also primes basophils for histamine and leukotriene release. In mice, IL-5 also induces the proliferation, differentiation, and immunoglobulin production of B cells especially B-1 cells that constitutively express IL-5 receptor alpha. IL-5 is primarily produced by CD4+ Th2 cells. Other cell types, including mast cells, visceral smooth muscle cells, bronchial epithelium, CD16+ NK cells, eosinophils and gamma delta T cells, can also produce IL-5. Canine IL-5 is synthesized as a 134 amino acid (aa) precursor that contains a 21 aa signal sequence and a 113 aa mature segment. Mature canine IL-5 shares 62%, 66%, 85%, 84%, 58%, and 56% aa sequence identity with mature human, guinea pig, porcine, feline, mouse, and rat IL-5, respectively. The receptor for IL-5 consists of a 60 kDa ligand-binding subunit (IL-5 R alpha ) and a 120 kDa signal-transducing subunit ( beta c) (1‑7).

Scientific Data Images for Canine IL‑5 Antibody
IL‑5 in Canine PBMCs.
IL-5 was detected in immersion fixed canine peripheral blood mononuclear cells (PBMCs) treated with calcium ionomycin and PMA using Goat Anti-Canine IL-5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1964) at 15 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; NL001) and counterstained with DAPI (blue). Specific staining was localized to cell surface.

Cell Proliferation Induced by IL‑5 and Neutralization by Canine IL‑5 Antibody.
Recombinant Canine IL-5 (1964-CL) stimulates proliferation in the TF-1 human erythroleukemic cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Canine IL-5 (30 ng/mL) is neutralized (green line) by increasing concen-trations of Goat Anti-Canine IL-5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1964). The ND50 is typically 0.75-3.0 µg/mL.
