S. frugiperda insect ovarian cell line Sf 21-derived recombinant human IL‑10 R alpha His22-Asn235 Accession # Q13651.1
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
<0.10 EU per 1 μg of the antibody by the LAL method.
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 0.03-0.1 µg/mL in the presence of 0.25 ng/mL Recombinant Human IL‑10 and 0.25 ng/mL LPS.
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.
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 Human IL‑10 R alpha Monoclonal Antibody (Catalog # MAB274). The ND50 is typically 0.03-0.1 µg/mL in the presence of LPS (0.25 ng/mL).

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.
