Abstract
Transduction with lentiviral vectors is a useful approach to study the molecular function of specific genes in mammalian cells. Here, we present a calcium phosphate-based transfection protocol that guarantees highly efficient production and delivery of lentiviral vectors in adherent cultured cells. We also describe in detail a direct lysis technique to measure protein expression, an optimized sulforhodamine B proliferation assay, and a step-by-step chromatin immunoprecipitation procedure to verify the binding of ETV5 to E2F1 first intron in SYO-1 sarcoma cells. For complete details on the use and execution of this protocol, please refer to Kingston et al. (2003),1 Ireton et al. (2002),2 Brown et al. (2009),3 DeSalvo et al. (2021),4 Vichai and Kirtikara (2006),5 and Boyer et al. (2005).6.
