Abstract
A family of cosmid vectors was constructed which contain replication origins (ori) derived from the multicopy plasmid R6K, a kanamycin resistance gene and two cos sites, permitting efficient library construction. Additional features of later constructs are (i) the presence of NotI sites flanking the site of insertion to allow intact excision of inserts, (ii) the facility for selective cloning of the ends of inserts for rapid chromosome walking, and (iii) the use of a mutated R6K ori leading to an increased copy number.Entities:
