Abstract

The disclosed invention involves a DNA encoding a hybrid tripartite protein comprising an amino portion consisting of from 6 to 28 amino acid residues from the N-terminal of a mature E. coli alkaline phosphatase, a central portion corresponding to a heterologous polypeptide and a carboxyl portion which consists of the remainder of the mature E. coli alkaline phosphatase, a different alkaline phosphatase or an enzymatically active fragment of either. The tripartite proteins produced with this DNA can be used as a diagnostic reagent and in the screening of nucleic acid libraries or in the selection of recombinant clones.
