| Further information: | The plasmid was created by replacing the NcoI/NheI fragment from pLT-mCASP-1p30-2 by the NcoI/NheI fragment from pEFBOSp30B, containing p30 mouse caspase-7 cDNA. The plasmid can be used to make in vitro translated p30 forms of the inserted caspase. The H6EK linker is composed of a hexameric histidine-encoding fragment (allowing the synthesis of affinity-tagged fusion proteins) followed by the enterokinase recognition site (allowing the precise release of the mature heterologous gene). This H6EK linker directly follows the ATG start codon. Transcriptional read-through from the promoters is minimized by the presence of a duplicated T7 transcription terminator and a duplicated fd transcription terminator. Read-through transcription from other plasmid promoters is minimized by the clockwise orientation of the PL and T7 promoters relative to the anticlockwise orientation of the replication origin. Furthermore, the plasmid is provided with an antisense phage T3 promoter. It also contains the replication origin of the single-stranded DNA phage f1, so that it can be rapidly switched between the plasmid and the phage mode (ssDNA) of replication. The latter requires infection with a helper phage, e.g. M13KO7. For T7 driven expression use a strain containing a controllable T7 RNA polymerase gene: preferably a pT7POL plasmid (Mertens et al., Biotechnology 13 (1995), 175-179) or e.g. BL21(DE3). Proceed as follows: first transform auxiliary plasmid, make competent cells again and then transform the expression plasmid. The nucleotide sequence of the mCASP-7 cDNA corresponds with the EMBL Nucleotide Sequence Database accession number Y13088.1. Name mentioned in Van de Craen et al. (1999) is pLTmCASP-7. Other names of the plasmid are pLT p30B and plt30Bsh. |
