IL-10 Protein, Human

IL-10 Protein, Human is an anti-inflammatory, immunomodulatory cytokine that regulates mucosal inflammation.

Interleukin 10 (IL-10) is an anti-inflammatory, immunomodulatory cytokine that regulates mucosal inflammation. A promising alternative is interleukin 10 (IL-10), a cytokine with multiple anti-inflammatory and immunoregulatory activities, including inhibition of T-cell/macrophage activation and proinflammatory cytokine synthesis^[1]. IL-10, a cytokine possessing strong anti-inflammatory properties, is under investigation for its therapeutic use as an immunosuppressant. The immunosuppressive actions of IL-10 and corticosteroids include inhibition of proinflammatory cytokine production by monocytes and polymorphonuclear leukocytes (IFN-γ, TNF-α, IL-1β, IL-6, GM-CSF) both at the protein and messenger RNA levels and prevention of mitogen-induced T-cell proliferation^[2].

1.The ED₅₀ is typically 1- 8 ng/mL as measured by MC/9-2 mouse mast cells in a cell proliferation assay.
2.Immobilized human IL10 at 10 μg/mL (100 μL/well) can bind Cynomolgus IL10RA-Fc and the EC₅₀ of Cynomolgus IL10RA-Fc is 0.24-0.56 μg/mL.
3.Immobilized human IL10 at 2 μg/mL (100 μL/well) can bind Cynomolgus IL10RA-Fc and the EC₅₀ of Cynomolgus IL10RA-Fc is 0.1-0.3 μg/mL.

Approximately 18.6 kDa

Greater than 90% as determined by reducing SDS-PAGE.

Lyophilized powder

Lyophilized after extensive dialysis against 20mM Tris, 20mM NaCl, pH 6.5. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
