Figure 3. Summary of the commonly used chemical transfection reagents.

Transfection reagents can be generally divided into liposomal or high-lipid based and non-liposomal based reagents. Non-liposomal reagents can be mixed protein-lipid reagents, non-liposomal lipids or non-protein non-lipid reagents like dendrimer.
