Cloned DNA: Human tumor necrosis factor cDNA (TNF); mature sequence
Promoter: Phage T4 gene 32 promoter (T4g32)
binding site:
Ribosome binding site (RBS) of the phage T4 gene 32 (T4g32)
Terminator: Phage fd terminator
Escherichia coli tryptophan operon terminator (trp); synthetic sequence
Selection marker: Ampicillin (amp)
Replicon: Escherichia coli plasmid pMB1 origin
Phage f1 origin
Host range: Escherichia coli
Parental clone: pMa58; pPLT4HTNFST8
Further information: This plasmid was constructed by inserting the EcoRI fragment from pPLT4HTNFST8, containing the phage T4 promoter, the hTNF mature sequence and the synthetic trpA terminator, clockwise into the unique EcoRI site of pMa58.
The unique SalI site of the polylinker of pMa58 was deleted.
Although the PstI restriction site of the ampicillin resistance gene was removed, the plasmid conserves its resistance to ampicillin, but it is sensitive to chloramphenicol (in sup(-) host strains).
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 this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT727505.1.
The nucleotide sequence of the hTNF cDNA corresponds with the EMBL Nucleotide Sequence Database accession number X01394.1.
Other name of the plasmid is pMaT4hTNFT.
