Abstract
A process for the production of a fusion protein comprising an active portion of a chloramphenicol acetyltransferase (CAT) protein and a polypeptide. The fusion protein may be purified using CAT substrate affinity chromatography. The eucaryotic polypeptide may be calcitonin or a dervative thereof such as calcitonin-glycine. Other polypeptides described include enzymes such as chymosin, prochymosin and preprochymosin, hormones such as ACTH, insulins, and growth hormones and antigenic polypetides such as foot and mouth disease virus antigenic polypetide. The fusion protein may be cleaved at a site susceptible to selective enzymic or chemical cleavage to produce free polypeptide. The fusion protein may be used as an immunogen.
