Abstract

New cloning vectors comprise at least one DNA sequence having (a) at least one promoter and operator derived from bacteriophage lambda and (b) at least one endonuclease recognition site (ERS) located less than 300 (pref. less than 150) base pairs from that portion of the DNA sequence comprising the promoter and operator. The vectors are esp. useful for expression of eukaryotic genes (e.g. for prodn. of interferon, hormones or antigenes) in prokaryotic hosts. The close proximity of the ERS and promoter sites improves the expression of these and other genes.
