- Abstract
The Type I Interferon cytokine family member, Interferon-α2b (hIFN-α2b), modulates a number of important biological mechanisms including anti-proliferation, immunoregulation and antiviral responses. Due to its role in the immune system, hIFN-α2b has been used as a therapeutic modulator in hepatitis C as well as some forms of leukaemia. Clinical grade hIFN-α2b is typically produced in bacterial expression systems that involves complex refolding protocols and subsequent loss of yields. In this study, we describe an expression and purification system for hIFN-α2b from mammalian cells. Application of the Trypsin-1 signal peptide-propeptide domain significantly improved the expression and secretion of hIFN-α2b from HEK293 cells. We established a simple purification strategy that yields homogenous, pure hIFN-α2b that is stable and biologically active., (Copyright © 2022 Elsevier Inc. All rights reserved.)
