Plasmid 11586: pSico PGK puro

• Gene/insert name: None
• Vector backbone: pSico PGK puro
  (Search Vector Database)
• Vector type: Mammalian Expression, Lentiviral, RNAi, Cre/Lox
• Backbone size (bp): 7703
• Modifications to Backbone: Puromycin is expressed from this plasmid as a selectable marker. Cre causes the puromycin gene to be recombined out of the construct, activating shRNA expression.

Comments: 

pSico PGK puro allows for conditional (Cre-Lox), stable expression of shRNAs for RNA interference in cells and transgenic mice. Addition of Cre TURNS ON shRNA expression.

The shRNA coding oligos have to be cloned into the HpaI and XhoI restriction sites. Oligo design information can be found on the author's map or on the Jacks Lab website http://web.mit.edu/ccr/labs/jacks/protocols/pSi...
