They have antiviral activity that it is mainly involved in innate immune response. The IFN-β family has 2 subtypes，which are IFN-β1 (IFNB1) and IFN-β3 (IFNB3) (a gene designated IFN-β2 is actually IL-6). IFN-β1 is used as a treatment for multiple sclerosis as it reduces the relapse rate.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eResearch_area\u003c\/b\u003e:Immunology\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurity\u003c\/b\u003e:\u0026gt; 97 % by SDS-PAGE and HPLC analyses.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSource\u003c\/b\u003e:Escherichia coli.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFull product name\u003c\/b\u003e:Interferon-Beta1b, humanIFN-beta1b\u003c\/p\u003e\u003cp\u003e\u003cb\u003eBiological activity\u003c\/b\u003e:Fully biologically active when compared to standard.
