WebApr 17, 2013 · Primers were designed to amplify the entire sequences of pBV-DsRed and pBV-OPH, except the cIts857 gene which encodes the repressor protein for transcriptional control in plasmid pBV220 (primers used were no. 5 and no. 6, see Table 1). The amplified fragment was then self-circularized to construct the plasmids pL-DsRed and pL-OPH. WebThe prophage lambda cIts857 induction test with Escherichia coli K12 envA uvrB as the lysogen has been successfully applied to the screening of sparingly water-soluble carcinogens that have been dissolved in dimethyl sulfoxide and metabolically activated with liver enzymes induced either with Aroclor 1254 or phenobarbital.
