Description
Pre-made lentiviral particles bicistronically express two individual proteins: nuclear permeable CRE recombinase and the GFP marker under the same suCMV promoter. A Puromycin marker was expressed under RSV promoter. Particles allows to sort or select transduced cells for long term expression via GFP signal or via Puromycin antibiotic selection. This particles was concentrated and buffer changed into PBS solution, best suitable for hard-to-transduced cell lines, serum sensitive cell lines and in vivo applications.
CRE and GFP are constitutively expressed in high level, and optionally, also can be used as tetracycline inducible expression as desired. GFP signal provides a convenient, realtime monitoring the particles performance.
Cre protein, from bacteriophage P1, catalyzes recombination between 34 base pair target sequences, named lox sites. CRE lentiviral particles can catalyze the jointing event In Vivo in the presence of lox sites. Purified CRE enzyme can joint individual plasmids containing lox sites.
