General description

Interleukin-10 (IL-10) is an immunosuppressive cytokine produced by a variety of mammalian cell types including macrophages, monocytes, T cells, B cells and keratinocytes. IL-10 inhibits the expression of proinflammatory cytokines such as interleukin-1 (IL-1) and tumor necrosis factor-α (TNF-α). Like IL-4, IL-10 enhances humoral immune responses and attenuates cell-mediated immune reactions. Human IL-10 active on murine cells, but murine IL-10 is inactive on human cells. The gene encoding this protein is localized on human chromosome 1q31-32. Recombinant human IL-10 is an 18.6 kDa protein of 161 amino acid residues.

Biochem/physiol Actions

Interleukin-10 (IL-10) is an anti-inflammatory protein that inhibits the expression of proinflammatory cytokines such as IL-1 and tumor necrosis factor-α (TNF-α). Like IL-4, IL-10 enhances humoral immune responses and attenuates cell-mediated immune reactions. It inhibits the production of IFN-γ and antigen-specific proliferation of type-1 T helper cells (Th1). It protects the host tissue from damage during immune responses. The protein has a role in modulating viral immunity. IL-10 enhances cytokine production, natural killer cell proliferation and cytotoxicity in vitro.

Physical form

Lyophilized from 20 mM Sodium Phosphate, pH 7.2.


Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
