Abstract
The efficacy of transfection reagents and nanoparticles is often assessed by measuring levels of expressed reporter protein. Fluorescence and luminescence based assays provide sensitive, quantifiable and repeatable approaches. The genes expressing reporter protein can be integrated into the cells to create stable reporter cell lines or can be expressed from a transfected plasmid. Green fluorescent protein, luciferase, and secreted alkaline phosphatase are well-established reporters with versatile applications. Monitoring changes in live cells during and after transfection offer opportunities to reveal related mechanisms, efficacy, and bottlenecks of transfection.
In this chapter, we describe the experimental setup and considerations for in vitro screening of delivery vectors. This can further be extended to measurements in reporter cell lines.
