- Overview
  - 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.

    Reactivity
    
    Human
    
    Purification
    
    >95% as determined by SDS-PAGE analysis.
    
    Formulation
    
    Lyophilized from a 0.2µm filtered solution of PBS, pH 8.0.
    
    Storage
    
    Lyophilized protein should be stored at -20°C for 1 year. Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months. Avoid repeated freeze/thaw cycles.
    
    Note
    
    Centrifuge at 3000 rpm for 5 mins before opening. It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 0.5 mg/mL and incubate the stock solution at RT for at least 20 mins to ensure sufficient re-dissolved. Do Not Vortex! Vigorous shaking may impair the biological activity of the protein.
    
    Molecular Weight
    
    The protein has a calculated MW of 18.3kDa. The protein migrates as 19kDa under reducing condition (SDS-PAGE analysis).
