Mouse IL-20 Antibody Summary

Species Reactivity

Mouse

Specificity

Detects mouse IL-20 in direct ELISAs and the Western blots. In direct ELISAs and Western blots, approximately 10% cross-reactivity with recombinant human IL-20 is observed.

Source

Polyclonal Goat IgG

Purification

Antigen Affinity-purified

Immunogen

E. coli-derived recombinant mouse IL‑20
Leu25-Leu176
Accession # Q9JKV9

Formulation

Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.

Endotoxin Level

<0.10 EU per 1 μg of the antibody by the LAL method.

Purity

Immunogen affinity purified

Applications

Recommended Concentration

Sample

Western Blot

0.1 µg/mL

Recombinant Mouse IL‑20 (Catalog # 1204-ML)

Neutralization

Measured by its ability to neutralize IL‑20-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 0.2-0.6 µg/mL in the presence of 10 ng/mL Recombinant Mouse IL‑20.

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.

Cell Proliferation Induced by IL‑20 and Neutralization by Mouse IL‑20 Antibody. Recombinant Mouse IL‑20 (Catalog # 1204-ML) 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 Mouse IL‑20 (10 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse IL‑20 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1204). The ND₅₀ is typically 0.2-0.6 µg/mL.

Background: IL-20

Mouse Interleukin 20 (IL-20) was identified by searching sequence databases for translated sequences with a signal sequence and amphipathic helices found in helical cytokines. Based on the human molecule, mouse IL-20 was discovered in a skin library. Mouse IL-20 is synthesized as a 176 amino acid (aa) precursor that contains a 24 aa signal sequence and a 152 aa mature segment. There are no N-linked glycosylation sites and it is doubtful that the native molecule is glycosylated. Although IL-20 is a distant member of the IL-10 family, it functions as a monomer. IL-20 shares less than 40% aa sequence identity with other IL-10 family members. Mouse and human IL-20 are 77% aa identical in the mature segment. IL-20 production has been found in skin and trachea. In particular, activated keratinocytes and, possibly, monocytes are reported to express IL-20. There are two heterodimeric receptor complexes for IL-20. The first complex is composed of IL-20 R alpha and IL‑20 R beta. The second complex is composed of IL-22 R and IL‑20 R beta. Whereas the IL‑22 R/IL‑20 R beta complex is shared with IL-24/mda-7, the IL‑20 R alpha /IL‑20 R beta complex is shared with both IL-19 and IL-24. Little is known about the function of IL-20. It is reported to induce the proliferation of multipotential hematopoietic progenitor cells, direct the differentiation and expansion of keratinocytes, and promote the release of proinflammatory mediators in keratinocytes and other IL-20 receptor expressing cells (1‑6).
