|Further information:||The plasmid was constructed by introducing the mouse OSKM cassette from pENTR1A-OSKM into the Cre excised pRMCE DV1 vector via Gateway LR recombination.
The monisite Gateway expression plasmid is a highly efficient Recombinase-Mediated Cassette Exchange (RMCE)-compatible Gateway vector and allows immediate ROSA26-based OSKM expression in mouse ES cells.
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.
This monosite Gateway expression vector, by co-transfection of a FlpE plasmid, can 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 causes ROSA26-based constitutive expression of the inserted OSKM cDNA.
The coding sequences in the OSKM cassette are connected via the self-cleaving T2A and F2A peptides, fulfilling the same role as an IRES, but with a much shorter sequence.
The G4 ROSALUC ES cells (LMBP 10507CB) are available at BCCM/GeneCorner as well.
Other name of the plasmid is Cre ex. pRMCE DV1 OSKM.
