Cloned DNA: Human interferon γ cDNA (IFNG); mutated mature sequence
Promoter: Phage λ major leftward promoter (λ PL)
Phage T7 gene 10 promoter (T7g10)
binding site:
Ribosome binding site (RBS) of the phage T7 gene 10 (T7g10)
Terminator: Phage T7 gene 10 terminator (T7g10)
Selection marker: Ampicillin (amp)
Replicon: Escherichia coli plasmid pMB1 origin
Host range: Escherichia coli; use strains with a cI function, cIts for PL controlled expression
Parental clone: pLT10T; pTrphIFNGHS2
Further information: The plasmid was constructed by inserting the SphI (blunt)/ BamHI fragment from pTrphIFNGHS2 containing the mature, mutated human interferon γ cDNA (hIFNG) into the ApaI (blunt)/BamHI opened pLT10T vector.
pLT10hIFNGT contains mutated mature human interferon γ cDNA (hIFNG); a unique SalI site and an extra HhaI site are created by silent mutations of amino acid 140 and 130-131 resp., the 3' UTR fragment is appox. 600 bp long.
This is an expression plasmid for mature hIFNG under control of the PL or the T7 promoter.
Restriction analysis suggests the presence of a XbaI site very close to the BamHI site, that is not retrieved in the sequence file.
For T7 driven expression use a strain containing a controllable T7 RNA polymerase gene, as well as a cI function: preferably a pT7POL plasmid (Mertens et al., Biotechnology 13 (1995), 175-179) or e.g. BL21(DE3)[pcI857]. Proceed as follows: first transform auxiliary plasmid, make competent cells again and then transform the expression plasmid.
