Abstract
Lambda derivatives are described that can be used for cloning DNA fragments of about 20 kilobase pairs (kb) generated by restriction enzymes EcoRi, HindIII, BamHI, MboI and BglII. Recombinants can be selected by their Spi- phenotype and their propagation is facilitated by the presence of a chi site.Entities:
