Abstract
Provided herein are a DNA fragment which contains a base sequence coding for a non-A non-B hepatitis-specific antigenic protein occurring in cells of the liver affected with non-A non-B hepatitis, an expression vector in which said DNA fragment is inserted into a cloning site present downstream from a promoter thereof, a transformant obtained by introducing said expression vector into a host, and a process for producing said antigenic protein which comprises providing said expression vector, transforming a host with said expression vector, culturing the transforming host and collecting the protein produced therein.
