Species of Origin
His Tag (N-term)
Lyophilized from a 0.2 µm filtered solution of PBS, pH 8.0.
>98% as determined by SDS-PAGE analysis.
The protein has a calculated MW of 14.93 kDa.
The protein migrates as 13-17 kDa under reducing condition (SDS-PAGE analysis).
Measure by its ability to induce proliferation in MO7e cells. The ED₅₀ for this effect is <0.25 ng/mL. The specific activity of recombinant human IL-9 is approximately >5 x10⁶ IU/ mg.
<0.01 EU per 1 µg of the protein by the LAL method.
Interleukin 9 (IL-9) is a pleiotropic cytokine that had pleiotropic functions in the immune system, has a molecular mass of 14.5 kDa. The major source of IL-9 is T lymphocytes. It is secreted by CD4+ helper cells that acts as a regulator of a variety of hematopoietic cells.
Cytokine P40, T-cell Growth Factors P40, Interleukin-7
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.
