SKU: LVP573-PBS Categories: ,

Description

Pre-made lentiviral particles expressing sequence verified CRE recombinase under the CAG promoter which is the strongest promoter in embryonic stem (ES) cells. CRE contains a NLS (nuclear localization signal) at its N-term.  This nuclear permeant CRE increases the recombination events in vivo. A Puromycin marker under RSV promoter, allows to select transduced cells for long term expression via Puromycin antibiotic. 

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.

This product constitutively expresses high level CRE enzyme in ES cells. This lentivirus was purified into PBS solution which is used for non-serum cell culture and hard-to-transduced cell types, or direcly used for in vivo application.
