|Further information:||The plasmid was constructed by replacing the 5' UTR and 3' UTR regions of mouse ROSA26 and the neomycin resistance gene in pROSA26-DV1 with the heterospecific FRT sites present in pROSALUC. A PGK-ATG sequence was included to ensure a proper trap-coupled RMCE reaction when targeted into mouse G4 ROSALUC ES cells.
pRMCE DV1 is a highly efficient Recombinase-Mediated Cassette Exchange (RMCE)-compatible, conditional Gateway destination vector.
This monosite Gateway destination vector contains the ccdB gene inserted between the attenuator sites attR1 and attR2.
The plasmid contains:
- two heterospecific Saccharomyces cerevisiae 2μ FLP Recombinase Target sites (one wt and one mutant FRT site)
- two bacteriophage P1 Cre recombinase target sites (loxP sites)
- two adjacent copies of the chicken β-globin 5' DNase I hypersensitive site 4 (5'HS4) insulator core sequence. Insulators are DNA sequences which possess the ability to protect expressing genes from inappropriate signals emanating from their surrounding environment by acting as barriers that prevent the advance of nearby condensed chromatin that may otherwise silence expression.
- a splice acceptor (SA) for linking the cDNA of interest to the endogenous ROSA26 promoter.
Next to this plasmid, an entry clone, containing the gene of interest flanked by the attL1-attL2 sites, is needed in the monosite approach to target the gene of interest to the endogeneous ROSA26 locus in mouse G4 ROSALUC ES cells.
The resulting monosite Gateway expression vector, by co-transfection of a FlpE plasmid, can subsequently be targeted to the ROSA26 locus of G4 ROSALUC ES cells using a trap-coupled RMCE approach, hereby restoring neomycin resistance.
Cre-mediated removal of the loxP-flanked stop cassette leads to ROSA26-based constitutive expression of the inserted cDNA.
The G4 ROSALUC ES cells (LMBP 10507CB) are available at BCCM/GeneCorner as well.
This Gateway destination vector is compatible with the human orfeome library which is also available at BCCM/GeneCorner.
The nucleotide sequence of this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT726806.1, except for the adjustments due to the implementation of the next-generation sequencing results.

|Authenticity test:||Restriction enzyme pattern analysed at GeneCorner: EcoRI, EcoRV, PvuII and XmnI.
This plasmid has also been fully sequenced but the NGS sequence data were unfortunately incomplete (because of homology regions: SV40 polyA and part of mPGK1 promoter).
