產(chǎn)品特性
| 純度 | >95% as determined by SDS-PAGE. Ni-NTA chromatography. |
| 內(nèi)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. |
| 運(yùn)輸 | Ambient temperature or ice pack. |
| 制劑 | The protein was lyophilized from a 0.2 μm filtered solution containing 1X PBS, pH 8.0. |
| 復(fù)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. |
背景介紹
Interferon alpha-1 or interferon alpha-D, encoded by the human IFNA1gene, is a member of the type I interferon family . It is expressed in peripheral blood leukocytes and lymphoblastoid cells. There are four highly conserved cysteine residues which form two disulfide bonds. One bond is a necessity for biological activity, which plays an critical role in conducting non-specific resistance against a variety of viral infections, and regulation of cell proliferation and modulates immune responses.
