IFN-alpha 2 (IFNA2), belongs to type I interferon family, is a protein secreted by cells infected by a virus and acting on other cells to inhibit viral infection[1]. IFN-alpha 2 increases the frequencies of cytotoxic CD8+ T cells and induces CD4+ T cell depletion[3]. IFN-alpha 2/IFNA2 Protein, Rhesus Macaque (HEK293, Fc) is produced in HEK293 cells with a C-terminal mFc-tag.
