Important messenger substance in human cells measured 'live' for the first time

Scientists have succeeded in making real-time measurements of changes in the concentration of the important messenger substance nitric oxide (NO) in human cells for the first time. The breakthrough, which has been published in the journal Nature Communications, was achieved by fusing two special proteins which then acted as a measurement probe. The fusion protein can be genetically coded and thus directly produced in the cells to be tested. This development paves the way for completely new insig
