Dankort Lab pLEG/pREG Modular Viral Vector System Pleg-Preg Logo


The LEG (Lentiviral Expression Gateway) is system a flexible vector system to allow the rapid production of lentiviral and retroviral (REG) vectors that express cDNAs with or without inhibitory RNAs (shRNAmirs) using Gateway technology. Click here to see full description.

These plasmids are originally described in:

A Modular Lentiviral and Retroviral Construction System to Rapidly Generate Vectors for Gene Expression and Gene Knockdown In Vitro and In Vivo. Geiling, B, Vandal G, Posner AR, de Bruyns A, Dutchak KL, Garnett, S, Dankort D. PLoS ONE 8(10): e76279. doi:10.1371/journal.pone.0076279.
