WebNov 1, 2024 · Superresolution microscopic techniques include photoactivated localization microscopy (PALM), which can localize a single protein by the stochastic activation of its fluorescence. In the determination of single-molecule localization by PALM, the number of molecules that can be analyzed per image is limited. Thus, many images are required to ... WebTechniques based on this strategy are often referred to as probe-based superresolution, and are commonly referred to by names photoactivated localization microscopy ( PALM ), …

PALM and STORM share a common fundamental principle, and numerous developments have tended to make the two techniques even more intertwined. Still, they differ in several technical details and a fundamental point. On the technical side, PALM is performed on a biological specimen using fluorophores expressed exogenously in the form of genetic fusion constructs to a photoactivatable fluorescent protein. STORM instead uses immunolabeling of endogenous mole… WebDec 1, 2010 · The system could be upgraded to a photoactivated localization microscopy (PALM) system by replacing the objective lens by one with a larger numerical aperture [20]. Moreover, lasers could provide ...
