OverviewpCDFDuet™-1 is designed for the coexpression of two target genes. The vector encodes two multiple cloning sites (MCS) each of which is preceded by a T7 promoter, lac operator, and ribosome binding site (rbs). The vector also carries the pCloDF13 replicon, lacI gene and streptomycin/spectinomycin resistance marker. This vector can be transformed into the same cell with pETDuet™-1, pACYCDuet™-1, and pRSFDuet™-1 or pCOLADuet™-1 for the coexpression of up to eight target genes. ORFs inserted into MCS-1 can be sequenced using the ACYCDuetUP1 Primer and DuetDOWN1 Primer. ORFs inserted into MCS-2 can be sequenced using the DuetUP2 Primer and T7 Terminator Primer.

The indicated constructs were transformed individually or together into BL21(DE3). Cultures were grown in TB plus phosphates plus glucose at 37°C to and Abs600 between 1.0 and 1.2. Target protein expression was induced by adding IPTG to a final concentration of 1 mM. Cultures were harvested by centrifugation 2.5 h after induction. Lysates were produced by sonication using equal volumes of 1% SDS and 2X SDS sample buffer. Equivalent amounts of protein (based on harvest ABS) were analyzed by SDS-PAGE (4-20% gradient gel) and stained with coomassie blue. To maximize band separation, proteins smaller than 25 kDa were allowed to migrate off the gel.
