Abstract

© Springer Science+Business Media New York 2015. Förster resonance energy transfer (FRET) biosensors represent invaluable tools to detect the spatiotemporal context of second messenger production and intracellular signaling that cannot be attained using traditional methods. Here, we describe a detailed protocol for the use of high content imaging in combination with FRET biosensors to assess second messenger production and intracellular signaling in a time-effective manner. We use four different FRET biosensors to measure cAMP levels, kinase (ERK and PKC), and GTPase activity. Importantly, we provide the protocols to express and measure these sensors in a variety of model cell lines and primary dorsal root ganglia neurons.
