A novel positive selection marker for Escherichia coli transformation was developed. The marker consisted of a DNA fragment encoding the C-terminal ribonuclease domain (CRD) of colicin E3 (colE3) and one or more amber stop codons between the initiation codon and the E3-CRD coding sequence. The toxicity of the marker was controlled by the suppressor activity the host cells possessed. This allowed both effective selection and propagation of the vector possessing the maker by selecting appropriate hosts from among those widely distributed: sup+ strains for selection and sup0 strains for propagation respectively. The insert DNA fragment was introduced onto the vector by replacing the marker DNA. The transformants harboring the vector with an insert grew, but those without an insert were effectively removed by the killing activity of E3-CRD encoded on the marker DNA. The marker was also successfully applied to lambda phage display vector.
