Abstract
New phage lambda based cloning vectors, Charons 36-40, have been constructed which allow cloning of large (up to 24 kb) DNA fragments with up to sixteen cloning enzymes. Several of these could not be used previously with lambda vectors. Clones produced with these vectors can be propagated under recombination deficient conditions. A novel polystuffer method has been developed that permits vector arms to be purified by simple precipitation and which allows reliable identification of clones that have reincorporated any part of the stuffer. Three of the vectors are available with amber mutations in essential genes.Entities:
