Rational engineering of ratiometric calcium sensors with bright green and red fluorescent proteins
Zhang, Redington & Gong develop FRET-based ratiometric calcium sensors with pairs of green and red fluorescent proteins. Their best performers, Twitch-GR and Twitch-NR inherit the superior photophysical properties of their constituent fluorescent proteins, enabling them to outperform existing ra...

| Sumario: | Zhang, Redington & Gong develop FRET-based ratiometric calcium sensors with pairs of green and red fluorescent proteins. Their best performers, Twitch-GR and Twitch-NR inherit the superior photophysical properties of their constituent fluorescent proteins, enabling them to outperform existing ratiometric calcium sensors in brightness, photobleaching, and signal fidelity metrics. |
