David M. Sabatini's laboratory developed reverse-transfection cell microarrays at the Whitehead Institute, publishing their work in 2001.
FuGENE is the name given to a series of non-liposomal transfection reagents produced by Fugent LLC of Wisconsin, USA, and marketed globally by Roche and Promega.
However, with the invention of different types of microarray printing systems, hundreds of transfection mixes (containing different DNA of interest) may be printed on the same slide for cell uptake of plasmids.
