产品特性
纯度 | >95% as determined by SDS-PAGE. Ni-NTA chromatography. |
内毒素 | <0.1 EU per 1 μg of the protein by the LAL method. |
保存 | Lyophilized protein should be stored at -5~-20°C for 1 year. Upon reconstitution, store at 2-8°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 -5~-20°C or -80°C for 3-6 months. |
运输 | Ambient temperature or ice pack. |
制剂 | The protein was lyophilized from a 0.2 µm filtered solution containing 1X PBS, pH 7.4. |
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. |
背景介绍
IFN-ω is a member of the type I interferon family, that can be induced by virus infected leukocytes and exert antiviral and anti-proliferative activities. IFN-ω shares about 75% sequence homology with IFN-α. There are two conserved disulfide bonds that are necessary for full biological activity.
