Hello everyone,
I would like to infect my NIH-3T3 cells with CMV promoter lentiviral particles to induce GFP expression. The particular plasmid is from Addgene (https://www.addgene.org/17446/). Does anyone have any estimates for an appropriate MOI when using 10 ug/mL of polybrene for these cells? If afterwards I only intend to collect a handful of colonies expressing GFP, do I need to find the optimal MOI for use?
