Product Description |
Recombinant Human Interferon omega-1 Protein is expressed from HEK293 with His tag at the C-terminus.It contains Leu22-Ser195. |
Product Background |
Human Interferon omega-1, a type I IFN, also known as IFN-ω1 or IFNW1, it contains a potential N-glycosylation site like human IFN-β. IFN-ω1 binds to the interferon alpha/beta receptor but not to the interferon gamma receptor. All IFN-ω genes analysed to date are devoid of introns. IFN-ω1 has been shown to be well-tolerated in man and to induce reductions of hepatitis C virus RNA levels in a series of human clinical trials. |

Formulation |
Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water. |
Stability And Storage |
Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. |
