IL-11 (Interleukin-11), Human
IL-11 is a cytokine and first isolated in 1990 from bone marrow-derived fibrocyte-like stromal cells. It was initially thought to be important for hematopoiesis, notably for megakaryocyte maturation, but subsequently shown to be redundant for platelets, and for other blood cell types, in both mice and humans. It is also known under the names adipogenesis inhibitory factor (AGIF) and was developed as a recombinant protein (rhIL-11) as the drug substance oprelvekin.

Endotoxin Test:
<0.1 EU per 1 μg of the protein by the LAL method.
Activity:
Measure by its ability to induce T11 cells proliferation. The ED50 for this effect is <0.2 ng/mL.
The specific activity of recombinant human IL-11 is approximately >1 x107 IU/mg.
Shipping Conditions:
Blue ice
Purity:
>98% as determined by SDS-PAGE.
Form:
Lyophilized
Storage Buffer:
Lyophilized from a 0.2 μm filtered solution of PBS, pH 8.0.
Reconstitution:
It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration not less than 200 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
Stability & Storage:
This product is stable after storage at:
• -20°C for 12 months in lyophilized state from date of receipt.
• -20°C or -80°C for 1 month under sterile conditions after reconstitution.
Avoid repeated freeze/thaw cycles.
