Escherichia coli β-lactamase promoter (amp)
Simian virus 40 early promoter (SV40 early)
binding site:
Terminator: Human granulocyte macrophage colony stimulating factor polyadenylation signal (GM-CSF polyA)
Herpes simplex virus (HSV) thymidine kinase polyadenylation signal (TK polyA)
Selection marker: Neomycin (neo; G418; kanamycin (kan))
Replicon: Escherichia coli plasmid pMB1 origin
Simian virus 40 bidirectional origin (SV40)
Phage f1 origin
Host range: Escherichia coli
Mammalian cells; SV40 permissive cells
Parental clone: pBK-CMV; pEF-BOS; pGBF-Kozakcre
Further information: The plasmid was constructed by inserting the phage P1 cre gene encoding recombinase (with Kozak consensus sequence) as a NheI/SpeI fragment of pGBF-Kozakcre between the XbaI sites of pBKEF-8.
pBKEF-8 was derived from pBK-CMV (Stratagene) by replacing the human CMV promoter and the SV40 polyA by the human EF1α promoter and the human GM-CSF polyA from pEF-BOS.
To generate stably transfected cells, use the NotI linearised plasmid.
pBKEF-Kozakcre is recommended to introduce partial deletions of loxP-flanked sequences in ES cells.
The nucleotide sequence of the cre gene corresponds with the EMBL Nucleotide Sequence Database accession number X03453.1.
