Sensor for Akt kinase activity in living cells

Case ID:
Web Published:

Researchers at Oregon Health & Science University have developed a novel Akt biosensor which provides a robust readout for the PI3-kinase signaling pathway in living cells without the use complex microscopy techniques. This biosensor allows quantitative tracking of Akt activity for days in individual cells within a population, and responds within minutes to changes in the signaling pathway that is altered in a variety of disease states and physiological conditions. The biosensor provides a greater dynamic range, is more sensitive and more specific to changes in Akt activity than other FRET reporters, and does not require multiple fluorescent channels thus allowing for a second fluorescent reporter to be used for orthogonal monitoring of biochemical activity.
