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.

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.
