Recombinant Human IFN-Beta1b protein

• Background:

  IFN-βs are proteins produced by many cell types including lymphocytes (NK cells, B-cells and T-cells), macrophages, fibroblasts, endothelial cells, osteoblasts and others. 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.

• Reconstitution:

  Lyophilized from a .2 μm filtered solution of PBS, pH 7.4.

• Molecular Weight:

  Approximately 2. kDa, a single non-glycosylated polypeptide chain containing 166 amino acids.

• CAS Number:

  9000-83-3
