Active Recombinant Human IFN-alpha 2b Protein

• Cat.No.: IFNA2-114H
• Product Overview: Recombinant Human IFN-alpha 2b Protein without tag was expressed in E. coli.

Specification

• Species: Human
• Source: E.coli
• Description: Interferon-alpha 2b (IFN-α 2b) is a type I interferon made by leukocytes during viral infection. The JAK-STAT pathway mediates the antiviral and anti-cell proliferation activities of IFN-α 2b. IFN-α proteins are widely used as standard treatments during antiviral and antineoplastic therapies. The IFN-α 2b variant differs from IFN-α 2a by one amino acid.
• Bio-activity: Viral CPE assay using EMC virus on A549 cells, ≤NA; ≥2.0 x 10^8 units/mg
• Molecular Mass: Monomer, 19.4 kDa (166 aa)
