3Rd Generation Lentivirus Protocol. Balance the ultracentrifuge tubes to within a difference of 0.01 g using sterile 1× pbs solution. Gently aspirate media, add 10 ml fresh dmem complete containing 25 μm cloroquine diphosphate and incubate ~5 hours.
Design of a trans protease lentiviral packaging system from retrovirology.biomedcentral.com
The transfer vector contains the transgene or silencing cassette to be delivered in a lentiviral backbone containing all. Incubate 4 hrs to overnight (16 hours) and replace with fresh medium. In this generation, the hiv tat gene (previously used to drive expression from the ltrs) has been removed, rev (which facilitates nuclear export) is expressed from a separate plasmid, and the promoter of the 5’ltr has been deleted to reduce its activity.

This protocol describes the reagents and steps to generate a single batch of high‐titer third‐generation lentivirus based on ultracentrifuge rotor volume capacity. You should do a titration of the 3 (or 4) plasmids, starting with some of the protocols given here each time you change any dna prep and find your best.
