IL-10 was first described as a cytokine that is produced by T helper 2 (Th2) cell clones. It inhibits interferon (IFN)-γ synthesis in Th1 cells, and therefore it was initially called cytokine synthesis inhibiting factor (CSIF).  Macrophages are the main source of IL-10 and its secretion can be stimulated by endotoxin (via Toll-like receptor 4, NF-κB dependent), tumor necrosis factor TNF-α (via TNF receptor p55, NF-κB-dependent), catecholamines, and IL-1. IL-10 controls inflammatory processes by suppressing the expression of proinflammatory cytokines, chemokines, adhesion molecules, as well as antigen-presenting and costimulatory molecules in monocytes/macrophages, neutrophils, and T cells. IL-10 inhibits the production of proinflammatory mediators by monocytes and macrophages such as endotoxin- and IFN-γ-induced release of IL-1α, IL-6, IL-8, G-CSF, GM-CSF, and TNF-α. In addition, it enhances the production of anti-inflammatory mediators such as IL-1RA and soluble TNFα receptors. IL-10 inhibits the capacity of monocytes and macrophages to present antigen to T cells. This is realized by down-regulation of constitutive and IFN-γ-induced cell surface levels of MHC class II, of costimulatory molecules such as CD86 and of some adhesion molecules such as CD58.

Product Details

Human IL-10, amino acids Ser19-Asn178 (Accession # NM_000572), was expressed in E.coli.
Molecular Mass
The 160 amino acid recombinant protein has a predicted molecular mass of 18 kD. The DTT-reduced protein migrates at approximately 18 kD and the non-reduced protein migrates at approximately 15 kD by SDS-PAGE. The N-terminal amino acid is Serine.
> 95%, as determined by Coomassie stained SDS-PAGE
0.1 µm filtered protein solution is in 10 mM NaH2PO4, 150 mM NaCl, pH 7.2.
Endotoxin Level
Less than 0.1 EU per µg protein as determined by the LAL method
500 µg/mL
Storage & Handling
Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% endotoxin-free BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week or stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles.
ED50 = 0.025 - 0.25 ng/mL as determined by the dose-dependent inhibition of IFN-γ induction in PHA activated human PBMC.

Antigen Details


IL-10 is produce by Th2 cells, macrophages, DCs, B cells, CD8+ T cells, regulatory T cells (Tregs), Th1 cells and Th17 cells. In addition, IL-10 is expressed by monocytes, B cells, eosinophils, and mast cells.

IL-10 is an immunoregulatory cytokine. Its main function is the limitation and termination of inflammatory responses and the regulation of differentiation and proliferation of several immune cells such as T cells, B cells, natural killer cells, antigen-presenting cells, mast cells, and granulocytes.
IL-10R is expressed in monocytes, NK, B and T cells. In addition, Langerhans cells, dermal dendritic cells, eosinophils, mast cells, and endothelial cells can respond to IL-10.
