RNAi-Ready pSIREN-RetroQ-ZsGreen derives from our original gene silencing retroviral vector RNAi-Ready pSIREN-RetroQ. pSIREN-RetroQ-ZsGreen is a self-inactivating retroviral expression vector designed to express a small hairpin RNA （shRNA） using the human U6 promoter. This vector is provided as a linearized vector digested with BamH I and EcoR I. It is used for targeted gene silencing when an annealed DNA oligonucleotide encoding an appropriate shRNA is ligated into the vector. The pSIREN-RetroQ-ZsGreen construct can be transfected as a plasmid expression vector. For generation of active retrovirus for infecting hard-to-transfect cell lines, transfect the pSIREN-RetroQ-ZsGreen construct into a retroviral packaging cell line and collect the viral supernatant.
