LambdaZLG6: a phage lambda vector for high-efficiency cloning and surface expression of cDNA libraries on filamentous phage.

We describe a vector, lambdaZLG6, combining the high efficiency of cDNA library cloning in bacteriophage lambda with filamentous phage display of cDNA-encoded products. The cDNAs are expressed as fusions to the 3' end of M13 gene VI. The lambdaZLG library is converted to a pZLG6-cDNA phagemid library by in vivo mass excision. Helper phage infection generates a library of phagemid particles displaying the cDNA-encoded products and containing the corresponding nucleotide sequences within.
