|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.
