| Further information: | The plasmid was constructed by inserting a 2564 bp HindIII-EcoRV(Eco32I) fragment from pVV202, containing the Gateway reading frame cassette B (rfB, from Invitrogen) in frame with the S. japonicum Sj26 antigen GST gene, into the HindIII-EcoRV(Eco32I) opened pSKoriTcat vector. pRH020 is a Gateway destination vector, containing the ccdB gene of the E. coli F plasmid, flanked by the bacteriophage λ attR recombination sites. A Gateway entry clone, containing the gene of interest flanked by the λ attL recombination sites, recombines with the attR sites of pRH020, replacing the ccdB gene. As a result, the gene of interest is fused to the C-terminal GST coding sequence. 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 does not permit counterselection as this resistance gene is also present in the plasmid backbone. Introduce the plasmid by electroporation, or through conjugation, using plasmid RK2/RP4 transfer functions (provided in trans by RK2/RP4, RK2/RP4-derived vectors, other replicons carrying RK2/RP4 transfer functions (e.g. pRK2073) or strains expressing the tra genes of RK2/RP4). When cloning a fragment downstream from the lac promoter it may be advisable to use lacI(q) strains in order to prevent fortuitous expression of a possibly noxious polypeptide. The nucleotide sequence of this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT726902.1. |
