Abstract

Abstract Disclosed is a complete description of the preparation of a novel, substantially pure polypeptide via recombinant DNA techniques utilizing any of an assortment of expression vectors and host cultures. The polypeptide, human immune (gamma) interferon (IFN-y), is isolated in substantially pure form and characterized in terms of DNA and amino acid sequences (see Figure 5), physical attributes and biological activity.
