A fluorogenic nanobody array tag for prolonged single molecule imaging in live cells [article]

Rajarshi Ghosh, Will Draper, J. Matthew Franklin, Quanming Shi, Jan Liphardt
2017 bioRxiv   pre-print
Prolonged single molecule imaging in live cells requires labels that do not aggregate, have high contrast, and are photo-stable.  ...  The photo-stability of ArrayG and consistently low background allowed us to continuously track single integrins for as long as 105 seconds (2100 frames).  ...  (a) Top: Representative time lapse images of spot bleach and recovery for ArrayG and ArrayD. ~ 10 sec time spacing between images.  ...
