Abstract
We have developed a general approach to the cloning of specific segments of the mammalian genome that involves a two-step purification of EcoRI fragments of mammalian DNA and their in vitro insertion into a suitably constructed EK2 derivative of bacteriophage lambda. The combination of fragment purification, exclusion of parental-type recombinants, and simple phage screening techniques permits the isolation of virtually any gene segment for which there is an identifying hybridization probe. We illustrate the approach by describing the cloning of an approximately 7000-base-long segment of mouse DNA containing globin and surrounding gene sequences.Entities:
