Abstract
The generation and selection of antibody libraries by phagemid-based phage display requires three components; namely, phagemid library, host bacterial cells, and helper phage. The use of helper phage is necessary for the selection of phagemid libraries by phage display because it provides all genes needed for production of infectious phage particles. Here, we describe the generation of high-titer helper phage preparations suitable for phagemid-based phage display. The approach is based on helper phage VCSM13, which includes a gene for kanamycin resistance and a mutated packaging signal that, in the presence of a phagemid with an unmutated packaging signal, favors the production of infectious phage particles with phagemid phenotype and genotype.
