IFN-alpha 4 (IFNA4), belongs to type I interferon family, is produced by macrophages with antiviral activities [1] . IFN-alpha 4/IFNA4 Protein, Human (HEK293, His) contains 166 a.a. (C24-D189), produced in HEK293 cells cells with a C-terminal His-tag.

IFN-alpha 4 (IFNA4; IFN-α4), belongs to the alpha/beta interferon (IFN) family, is produced by the macrophages with antiviral activities. Interferon (IFN) is originally identified as a substance ‘interfering’ with viral replication in vitro. IFN-α/β and related molecules are classified as type I IFNs, as for the other two types of type II IFN (IFN-γ) and type III IFNs (IFN-λ), respectively [1] . Interferon alpha (IFNa) shows significant biological activity in various cancers, paticularly haematological malignancies such as hairy cell leukaemia and chronic myelogenous leukaemia [2] . IFN-alpha 4 is the subtypes dominates in IFN-alpha, whose the response with IFNA5, IFNA7, and IFNA14 accounting for up to 85% of the subtypes expressed by Peripheral blood mononuclear cells (PBMCs) [3] . IFN-alpha 4 is promoted by interferon (IFN) regulatory factors (IRFs), especially IRF-1 and IRF-7 [5] [6] . And it exhibits function by inhibiting virus RNA replication and enhances human natural killer cytotoxicity against virus [4] [7] . As for a wildly use of IFN in animal model, the sequence of amino acids in IFNA4 protein of human is very different from mouse (57.07%) and rat (57.98), respectively.
