![pCLXSN Retrovirus Expression Vector [NBP2-29500] - Schematic presentation of pCLXSN vector: CMV immediate early enhancer-promoter allows highefficiency transcription in 293 cells. However, this is lost during viral replication. Hence, the gene of interest cloned into Eco RI, Xho I, or Bam HI cloning site is driven by Moloney MLV and murine sarcoma virus LTR (RU5).](http://images.novusbio.com/fullsize/pCLXSN-Retrovirus-Expression-Vector-NBP2-29500-img0001.jpg "pCLXSN Retrovirus Expression Vector [NBP2-29500] - Schematic presentation of pCLXSN vector: CMV immediate early enhancer-promoter allows highefficiency transcription in 293 cells.
