Recombinant human interferon-alpha 2b (IFNα2b) is expressed in CHO cells to ensure proper folding, glycosylation, and consistent biological activity. Produced in a tag-free format, this protein preserves its native sequence and structure, making it highly suitable for antiviral research, immune modulation studies, and therapeutic development.

IFNα2b is a type I interferon with potent antiviral, antiproliferative, and immunomodulatory properties. It is secreted by leukocytes in response to viral infections and plays a key role in activating innate immune defenses, enhancing NK cell activity, and upregulating antigen presentation pathways. Recombinant human IFNα2b is widely used in virology research, cancer immunotherapy studies, autoimmune disease models, and drug discovery.
