Advanced RNAi Applications — Difficult Cell Types FAQs

The lentiviral particles are pseudotyped with VSV-G Protein. This allows transduction of a wide range of cell types. We have listed cell types that have been successfully transduced with the pLKO.1-puro lentiviral constructs.

We have a list of cell types that have been successfully transduced by pLKO.1-puro based lentiviral particles.

Yes, multiple researchers have demonstrated that MISSION® shRNA lentiviral particles can transduce neuronal cells, both in culture and in vivo. That said, expression of GFP in some species has proven difficult when driven from a CMV promoter.

Here is a reference describing how lentiviral shRNA has been used to stably transduce monocytic cells: Unwalla, H.J. et al. Negative feedback inhibition of HIV-1 by TAT-inducible expression of siRNA. Nat. Biotechnol. Dec, 2004 22(12), 1573-8. Epub 2004 Nov 28.1

We suggest optimizing your experimental conditions with the TurboGFP Control Virus (Product No. SHC003V). You can easily see the transduction efficiency obtained with different lentiviral MOIs in your cells.

Most cell lines are NOT ideally suited to produce lentivirus with the MISSION® shRNA library. We suggest using an HEK-293T cell line for generating virus particles. In addition, you'll need to use packaging vectors derived from HIV. We recommend using our Packaging Mix (Product No. SHP001) for optimal high titer virus production.
