Further information: | The plasmid was constructed as follows: 1) the kanamycin resistance gene was removed from pECFP-C1 (Clontech) by cutting with BsaI and ClaI; 2) the ampicillin resistance gene was amplified from a pBluescript vector (Stratagene) and cloned into the blunted pECFP-C1 vector, sense relative to the SV40 early promoter, resulting in pECFP-C1amp; 3) the Gateway reading frame cassette B (rfB, from Invitrogen) was cloned between the blunted BglII and BamHI sites of pECFP-C1amp, resulting in pdECFP. pdECFP is a Gateway destination vector, containing the ccdB gene flanked by the bacteriophage λ attR recombination sites. pdECFP is designed for fusing a gene of interest to the C-terminus of the ECFP variant of the A. victoria GFP DNA according to the Gateway Cloning Technology (Invitrogen), and for high-level, constitutive, native expression of this gene in mammalian cells under control of the human CMV-IE promoter and enhancer. A Gateway entry clone, containing the gene of interest flanked by the λ attL recombination sites, recombines with the attR sites of the destination vector, replacing the ccdB gene. Standard E. coli strains with the unreacted destination vector or with the by-product plasmid retaining the ccdB gene will fail to grow. Thus, this negative selection provides high-efficiency recovery of only the desired clones. The chloramphenicol resistance gene located between the two attR sites permits counterselection. ECFP is a cyan fluorescent variant of the wild type GFP that has been optimized for brighter fluorescence and higher expression in mammalian cells (excitation maximum = major peak at 433 nm and a minor peak at 453 nm; emission maximum = major peak at 475 nm and a minor peak at 501 nm) and which contains the amino acid substitutions Phe-64 to Leu, Ser-65 to Thr, Tyr-66 to Trp, Asn-146 to Ile, Met-153 to Thr and Val-163 to Ala. This Gateway destination vector is compatible with the human orfeome library which is also available at BCCM/GeneCorner. The nucleotide sequence of this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT727259.1. Nucleotide sequence analysis by BCCM/GeneCorner proved that the ampicillin resistance coding sequence, but not the ampicillin promoter, is inserted antisense relative to the SV40 early promoter. Although a BLAST search didn't allow the identification of a promoter upstream of the ampicillin resistance coding sequence, the construct-carrying E. coli culture proved to grow in the presence of this antibiotic. Other names of the plasmid are pdECFP-C1amp and pDEST-ECFP. |
