Further information: This plasmid was developed as a vector for gene 'knock-out' experiments in mammalian cells by double homologous recombination (positive and negative selection).
The neomycin resistance gene contains some modifications at the start of the coding sequence as compared to the wild type gene.
As the plasmid contains the mouse PGK1 promoter and the mouse PGK1 polyA sequence twice, one should be aware of the possibility of deletions due to homologous recombination.
When cloning a fragment downstream from the lac promoter it may be advisable to use lacI(q) strains in order to prevent fortuitous expression of a possibly noxious polypeptide.
The nucleotide sequence of this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT727535.1.
The nucleotide sequence of this plasmid was compiled based on the publications mentioned in 'Plasmid reference' and 'Related reference'.
Unpublished sequences and linkers have been sequenced at the Department of Biomedical Molecular Biology, Ghent University, Belgium.
The linker region between the 3' UTR of the mouse PGK1 gene and the mouse PGK1 promoter has been sequenced at Roche Research Ghent.
