Changes known as epigenetic modifications play an important role in cancer development. Being able to analyze them quickly and reliably could contribute significantly to the further development of personalized therapy. A research team from the Institute of Physiology at the University of Freiburg has now succeeded in characterizing the chemical changes in proteins that are typical for epigenetic modifications using nanopore analysis. The researchers have published their research results in the Journal of the American Chemical Society (JACS).
