Species of Origin
Human
Expression System
Escherichia coli
-
Affinity Tag
His Tag (C-term)
Storage Buffer
Lyophilized from a 0.2 µm filtered solution of PBS, pH 8.0.
-
Purity
>97% as determined by SDS-PAGE analysis.
Molecular weight
The protein has a calculated MW of 18.3 kDa.
The protein migrates as 19 kDa under reducing condition (SDS-PAGE analysis). -
Activity
Measured by its ability to induce PHA-activated human PBMCs proliferation. The ED₅₀ for this effect is 0.5-4 ng/mL. The specific activity of recombinant human IL-7 is > 1 x 10⁸ unit/mg, which is calibrated against the human IL-7 WHO Reference Reagent (NIBSC code: 90/530).
Endotoxin Level
<0.05 EU per 1 µg of the protein by the LAL method.

Background
Interleukin-7 (IL-7) is a multipotent cytokine belonged to one of the members of IL-2 superfamily. IL-7 has diverse effects on the hematopoietic and immune regulations. IL-7 is a trophic factor that is necessary for both B cell and T cell proliferation and development. In addition, it presents potential antitumor effects in tumors such as glioma, melanoma, lymphoma, leukemia, prostate cancer, and glioblastoma.
Synonyms
