Plasmid name: pMcMTNFm2t (LMBP 2655)
|Price category:||Cat. 1 (cf. price list)|
|Status:||GeneCorner non-core plasmid|
|Cloned DNA:||Mouse tumor necrosis factor cDNA (Tnf, TNF); mutated mature sequence|
|Terminator:||Phage fd terminator|
|Selection marker:||Chloramphenicol (cam)|
|Replicon:||Escherichia coli plasmid pMB1 origin
Phage f1 origin
|Host range:||Escherichia coli|
|Further information:||This plasmid was constructed by site-specific mutagenesis, where the nucleotide sequences of codons 2 and 4 of mature mouse TNF (AGA, coding for Arg, and TCT, coding for Ser) were converted to TGA (opal) and TAG (amber), respectively. This mutagenesis creates a unique BclI restriction site.
Restriction enzyme digestions revealed that approx. 60 nucleotides are missing from the 3' untranslated region of mouse TNF, including the 3'-terminal (supposedly restored) EcoRI site.
After mutagenesis, use mutS strains for primary transformation (e.g. sup(-) strain WK6mutS, sup(+) strain BMH71-18mutS); for segregation of possible mutants: sup(-) strains (e.g. WK6).
The nucleotide sequence of the wild type mouse TNF corresponds with the EMBL Nucleotide Sequence Database accession number M11731.1.
