pSB6K1 - a pBR322-based vector with Kanamycin resistance

Improvement of pSB6A1

ThisTo extend the usage of BioBrick-compatible pBR322-based vector (Part:pSB6A1) we changed the promoter of lac to ldhp and an antibiotic of ampicillin to kanamycin or chloramphenicol to generate two plasmid backbones of pSB6K1 (Part:BBa_K3728009) and pSB6C1 (Part:BBa_K3728010) and a composite part of ldhp-RFP-Tr/pSB6C1 (Part:BBa_K3728013).

Construction of Plasmid Backbones

ThisTo generate the pBR322-based backbone, pSB6A1 was amplified as a whole backbone to exclude AmpR coding region by PCR with a primer set of pSB6A1-Amp-NheI-F/pSB6A1-Amp-NsiI-R to generate NheI and NsiI restriction enzyme sites . And the antibiotics of KanR and CmR genes were cloned by PCR using pUCIDT-Kan and pSB1C3 as templates, respectively, along with primer sets to create XbaI and PstI sites. The assembled constructs were generating scars of NheI/XbaI and NsiI/PstI to eliminate XbaI and PstI for standard iGEM BioBrick Assembly Rule. The plasmids were confirmed by colony PCR check and able to transform E.coli DH5α on the agar plates with corresponding antibiotics.
