The complete nucleotide sequence (5793 bp) of the cosmid vector pTL5 and the origin of its genetic components has been determined. Cosmid pTL5, a derivative of cosmid vector pHC79, is composed of genetic components from pBR322, bacteriophage lambda and the hybrid lambdoid bacteriophage Charon (Ch) 4A cohesive ends (cos) region. The Ch4A cos region contains genetic components from two bacterioph...
