Finding the right transfection reagent is a key step in your cell-based expression studies. You need a reagent that will effectively deliver your construct without causing cellular changes that could interfere with the interpretation of your results. In addition to these essentials, it’d be nice to find a reagent that is easy-to-use (e.g. serum tolerant), has been tested in your cells of interest, and that can carry you all the way through your experimental design, perhaps as far as clinical trials. It may sound like too much to ask for, but the reagents listed below offer easy-to-perform, safe and effective transfection. Check them out and find the one that best suits your experimental needs.
