โฆ Synopsis
A genetic procedure for selection of specific lambda clones, by homologous recombination between lambda clones from a gene clonotheque and sequences cloned into a plasmid, was developed. Resulting clones are isolated in transduction experiments by plating infected Escherichia coli cells under conditions selecting for the antibiotic resistance marker carried by the plasmid. The feasibility of the method was demonstrated in a model test system as well as by isolation of alpha-interferon-specific sequences from the human gene clonotheque.

A 50-fold (or greater) increase in the production of phage 21 repressor was obtained by construction of a plasmid in which the 21cI (repressor) gene could be transcribed from lambdaPL. The enhancement due to increased 21cI gene copy number and transcription from lambdaPL were at least five-fold and
