CC   [1] inserted strong promoters from T7 and lambda into pBR322
CC   derived promoter-probe vectors. The inserted promoters, which
CC   occurred in dissimilar environments, served as promoters for the
CC   pBR322 tetracycline resistance operon.  Promoter strength was
CC   measured by Tc resistance.  Plasmids containing T7 A2 promoters
CC   appeared to confer less Tc resistance than those containing A3
CC   promoters.
