If you are trying to make an inducible lentivirus for overexpression of a gene instead of knockdown, there are a few nice commercial systems available (we use Clontech&39;s 3G system). Lenti-XLentiviral Expression Systems User Manual PT5135-1 Published Octo United States/Canada 800. TakaraBio Company 1290 Terra Bella Ave.
When a repair template is present, the cell may repair a DSB using homology-directed repair (HDR) instead of NHEJ. Cut sites of enzymes that you select are highlighted to help guide your work. Catalytically dead dCas9 fused to a transcriptional activator peptide can increase transcription of a specific gene. This technique creates diverse populations of mutants for directed evolution. 631187), can generate lentiviral titers that are superior to most other commercially available lentiviral packaging systems. Catalytically dead dCas9 fused to a cytidine deaminase protein becomes a specific base editor that can alter DNA bases without inducing a DNA break. Using these systems, your target cells will express high levels of your GOI, but only when cultured in the presence of doxycycline (Dox) (Figure 1).
