ABSTRACT:
Methods are provided for producing .alpha.-1-antitrypsin in host cells and for selecting transformed cells comprising the step of transforming the host cell with a DNA molecule comprising a gene which complements a deficiency in the host cell. The host cell is a strain having a deficiency in a function necessary for normal cell growth. The gene in the DNA molecule, such as a plasmid, which complements the deficiency serves as a selectable marker whereby the growth conditions for selection may comprise a conventional complex medium.
