Scientific Data Images for Canine IL‑5 Antibody

IL-5 antibody in Canine PBMCs by Immunocytochemistry (ICC).

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.

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.

Applications for Canine IL‑5 Antibody

Application
Recommended Usage

Immunocytochemistry

5-15 µg/mL
Sample: Immersion fixed canine peripheral blood mononuclear cells (PBMCs) treated with calcium ionomycin and PMA

Western Blot

0.1 µg/mL
Sample: Recombinant Canine IL‑5 (Catalog # 1964-CL)

Neutralization

Measured by its ability to neutralize IL‑5-induced proliferation in the TF‑1 human erythroleukemic cell line. Kitamura, T. et al. (1989) J. Cell Physiol. 140:323. The Neutralization Dose (ND50) is typically 0.75-3.0 µg/mL in the presence of 30 ng/mL Recombinant Canine IL‑5.

Background: IL-5

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).
