Isolation and Bacterial Expression of a Murine Alpha Leukocyte Interferon Gene

Abstract
A murine alpha interferon gene (MuIFN-αA) was isolated from a murine genomic DNA library in phage lambda. The gene was cloned and its sequence determined. It was expressed in Escherichia coli under the control of the trp promoter/operator which resulted in antiviral activity on mouse L-cells. MuIFN-αA exhibits 60% homology to HuIFN-αA at the amino acid level.
