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 2 μg/mL (100 μL/well) can bind Cynomolgus IL10RA-Fc and the EC₅₀ of Cynomolgus IL10RA-Fc is ≤1 μg/mL.
3.Human IL-10 inhibits LPS-induced secretion of IL-6 by RAW264.7 cells. The ED₅₀ for this effect is 0.1559 ng/mL. Corresponding to a specific activity is 6.414×10^6 U/mg.

Approximately 18 kDa

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

Lyophilized powder

Lyophilized after extensive dialysis against 20mM Tris, 20mM NaCl, pH 6.5, 5% Trehalose, 5% Mannitol, 0.01% Tween-80 or PBS, pH 7.4, 5% Trehalose, 5% Mannitol or PBS, pH 7.4, 0.1% SKL.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. 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.
