Recombinant Human IL-2 重组人白介素-2

描述（Description）

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 exerts cytotoxic activity against CD8+ T cells and induces CD4+ T cell depletion[3]. IFN-alpha 2b/IFNA2 Protein, Human contains 165 a.a. (C24-E188), is a protein produced in E. coli with tag free.
