生物活性 | Measure by its ability to induce TNF alpha secretion in RAW264.7 cells. The ED50 for this effect is < 10 μg/mL. |
纯度 | > 98% as determined by SDS-PAGE. Ni-NTA chromatography |
内毒素 | < 0.1 EU/μg |
制剂 | The protein was lyophilized from a 0.2 μm filtered solution containing 1 × PBS, pH 8.0. |
复融 | It is recommended to reconstitute the lyophilized protein in sterile water to a concentration not less than 100 μg/mL. Do Not Vortex! Vigorous shaking may impair the biological activity of the protein. |
储存条件 | Lyophilized protein should be stored at -5~-20℃ for 1 year. Upon reconstitution, store at 2-8℃ 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 -5~-20℃ or -80℃ for 3-6 months. |
运输条件 | Ambient temperature or ice pack. |
有效期 | 12个月 |
背景介绍 | Interleukin-32α (IL-32 α) is one of approximately 6 splice variants of a gene cloned from the human lung carcinoma stable transfectant, A549-Rβ. IL-32 α has been shown to induce IL-8, TNF-α, and MIP-2 production from human & mouse macrophage cell lines. It is up-regulated in activated T- & NK-cells, and IFN-g-treated epithelial cells. |
