Scientific Data Images for Human IL-10 R alpha Antibody
IL-10 R alpha in Human PBMCs.
IL‑10 R alpha was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) using 15 µg/mL Goat Anti-Human IL‑10 R alpha Antigen Affinity-purified Polyclonal Antibody (Catalog # AF‑274‑NA) for 3 hours at room temperature. Cells were stained (red) and counterstained (green). View our protocol for Fluorescent ICC Staining of Non-adherent Cells.
IL‑10 Inhibition of IL‑1 beta secretion and Neutralization by Human IL‑10 R alpha Antibody.
Recombinant Human IL-10 (Catalog # 217-IL) inhibits IL-1 beta secretion in LPS-activated human peripheral blood mononuclear cells (PBMC) in a dose-dependent manner (orange line), as measured by the Human IL-1 beta/IL-1F2 Quantikine ELISA Kit (Catalog # DLB50). IL-1 beta secretion inhibited by Recombinant Human IL-10 (0.25 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human IL-10 Ra Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-274-NA). The ND50 is typically 20-40 µg/mL in the presence of LPS (0.25-3 ng/mL).Applications for Human IL-10 R alpha Antibody

Neutralization
Measured by its ability to neutralize IL‑10 R alpha-mediated IL‑10 response in LPS-activated human peripheral blood mononuclear cells (PBMC) [Ralph, P. et al. (1991) J. Immunology 148:808]. The Neutralization Dose (ND50) is typically 20-40 µg/mL in the presence of 0.25 ng/mL Recombinant Human IL‑10 and 0.25-3 ng/mL LPS.

Background: IL-10 R alpha
IL-10, initially designated cytokine synthesis inhibitory factor (CSIF), is a potent immunosuppressant of macrophage functions. IL-10 is also a pleiotropic cytokine with multiple immunostimulatory as well as immunosuppressive effects on a variety of other cell types. IL-10 binds specifically and with high affinity to cell-surface receptors. Mouse and human cDNA clones encoding the ligand-binding IL-10 receptor (IL-10 R) have been isolated. The IL-10 R mRNA has been detected in all cell types that are known to respond to IL-10.
Human and mouse IL-10 receptors are structurally related to the IFN-gamma receptor. These receptors are members of the class II subgroup of the cytokine receptor superfamily. The deduced amino acid sequence of human IL-10 R is approximately 60% identical to mouse IL-10 R. Although human IL-10 has cross-species activities and is active on mouse cells, mouse IL-10 is species-specific in its actions and does not bind to the human IL-10 receptor. The human IL-10 R gene has been mapped to chromosome 11q23.3. Recombinant IL-10 soluble receptor, consisting of the extracellular domain of IL-10 R, binds IL-10 with high affinity in solution and is a potent IL-10 antagonist.
