Scientific Data Images for Human IL-24 Antibody

Cell Proliferation Induced by IL‑24 and Neutralization by Human IL‑24 Antibody.

Cell Proliferation Induced by IL‑24 and Neutralization by Human IL‑24 Antibody.

Recombinant Human IL-24 (Catalog # 1965-IL) stimulates proliferation in the BaF3 mouse pro-B cell line co-transfected with human IL-20 Ra and IL-20 R beta in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human IL-24 (2 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human IL-24 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1965). The ND50 is typically < 0.6 µg/mL.
Human IL-24 ELISA Standard Curve

Human IL-24 ELISA Standard Curve

Recombinant Human IL‑24 (Catalog # 1965-IL) was serially diluted and captured by Mouse Anti-Human IL‑24 Monoclonal Antibody (Catalog # MAB19652) coated on a Clear Polystyrene Microplate (Catalog # DY990). Goat Anti-Human IL‑24 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1965) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998)

Applications for Human IL-24 Antibody

Application
Recommended Usage

CyTOF-ready

Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

Intracellular Staining by Flow Cytometry

2.5 µg/106 cells
Sample: Human peripheral blood mononuclear cells fixed with paraformaldehyde and permeabilized with saponin

Western Blot

0.1 µg/mL
Sample: Recombinant Human IL‑24 (Catalog # 1965-IL)

Neutralization

Measured by its ability to neutralize IL‑24-induced proliferation in the BaF3 mouse pro‑B cell line co-transfected with human IL‑20 R alpha and IL‑20 R beta. The Neutralization Dose (ND50) is typically < 0.6 µg/mL in the presence of 2 ng/mL Recombinant Human IL‑24.

Background: IL-24

Interleukin 24 (IL-24), also known as mda-7 (melanoma differentiation associated gene-7), is a member of the IL-10 family of helical cytokines. The IL-24 gene encodes a precursor protein of 207 amino acids that contains a 48 amino acid (aa) signal sequence and an 18 kDa, 158 aa mature segment. There are three potential N-linked glycosylation sites, at least one of which is used. When secreted, IL-24 is a 35-40 kDa phosphorylated glycoprotein that apparently can exist as either a monomer or dimer. It is suggested that glycosylation is essential for activity. Mature human IL-24 shares 69% aa sequence identity with mouse and rat IL-24. Human IL-24 is also active in rodent systems. Cells known to express IL-24 include B cells, CD4+ T cells, NK cells, lymph node dendritic cells, monocytes, melanocytes, and melanoma cells. Functionally, IL-24 has diverse activities. At low concentrations on monocytes, it induces type I proinflammatory cytokines such as IFN-gamma, IL-1 beta, IL‑12, and TNF-alpha. At high concentrations, it is a strong inducer of apoptosis in tumor cells but not normal cells. IL-24 also has anti-angiogenic properties. It directly binds IL-24 receptors on endothelial cells, activating STAT3 and blocking their differentiation. IL-24 binds and signals through two heterodimeric receptor complexes. One complex is the combination of IL-20 R alpha and IL-20 R beta, which is shared with IL-19 and IL-20. The second complex is a combination of IL-22 R and IL-20 R beta, which is shared with IL-20.
