产品简介
背景描述 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.
别称 interleukin 7, Lymphopoietin 1(LP-1), pre-B-cell factor, IL7
蛋白编码 P13232
分子量 The protein has a calculated MW of 18.3 kDa. The protein migrates as 19 kDa under reducing condition (SDS-PAGE analysis).
表达系统 Escherichia coli
纯度 >95% as determined by SDS-PAGE analysis.
生物活性 Measured by its ability to induce PHA-activated human PBMCs proliferation. The ED₅₀ for this effect is <0.8 ng/mL. The specific activity of recombinant human IL-7 is > 1 x 10⁸ units/mg.
内毒素检测 <0.05 EU per 1 μg of the protein by the LAL method.

产品形式 Lyophilized from a 0.2 µm filtered solution of PBS, pH 8.0.
产品储存/运输
储存 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.
运输 Blue Ice
产品使用
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 min to ensure sufficient re-dissolved. Do Not Vortex! Vigorous shaking may impair the biological activity of the protein.
