Purity: > 90% by SDS - PAGE Format: Liquid. In Phosphate Buffered Saline (pH 7.4) containing 10% glycerol.. IFNA7, also known as interferon alpha-7, is a member of the interferon family. Interferon promotes the production of two enzymes, protein kinase and oligoadenylate synthetase. They allow the cells to communicate with the protective barrier of the immune system to eradicate pathogens or tumors. IFNs are divided on the sequence of amino-acids into three groups: Alpha, Beta and Gamma interferons. IFN-alpha has both anti-viral and immunomodulatory activities on target cells, and increases the awareness of infection or tumor cells by elevating antigen presentation to T lymphocytes. This protein has both anti-viral and immunomodulatory activities on target cells and involved both in ligand binding and signal transduction. Recombinant human IFNA7, fused to His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques.
