Inducible fluorescent speckle microscopy
The understanding of cytoskeleton dynamics has benefited from the capacity to generate fluorescent fiducial marks on cytoskeleton components. Here we show that light-induced imprinting of three-dimensional (3D) fluorescent speckles significantly improves speckle signal and contrast relative to classic (random) fluorescent speckle microscopy. We predict theoretically that speckle imprinting usin...
متن کاملQuantitative fluorescent speckle microscopy of cytoskeleton dynamics.
Fluorescent speckle microscopy (FSM) is a technology used to analyze the dynamics of macromolecular assemblies in vivo and in vitro. Speckle formation by random association of fluorophores with a macromolecular structure was originally discovered for microtubules. Since then FSM has been expanded to study other cytoskeleton and cytoskeleton-binding proteins. Specialized software has been develo...
متن کاملHow we discovered fluorescent speckle microscopy
Fluorescent speckle microscopy (FSM) is a method for measuring the movements and dynamic assembly of macromolecular assemblies such as cytoskeletal filaments (e.g., microtubules and actin) or focal adhesions within large arrays in living cells or in preparations in vitro. The discovery of the method depended on recognizing the importance of unexpected fluorescence images of microtubules obtaine...
متن کاملNew Directions for Fluorescent Speckle Microscopy
Fluorescent Speckle Microscopy (FSM) is a technology for analyzing cytoskeleton dynamics, giving novel insight into their roles in living cells. New applications of FSM, together with the development of computer-based FSM image analysis, will make FSM the first microscopy-based method to deliver quantitative kinetic readouts at high spatial and temporal resolution for a wide variety of macromol...
متن کاملFluorescent speckle microscopy of microtubules: how low can you go?
Fluorescent speckle microscopy (FSM) is a new technique for visualizing the movement, assembly, and turnover of macromolecular assemblies like the cytoskeleton in living cells. In this method, contrast is created by coassembly of a small fraction of fluorescent subunits in a pool of unlabeled subunits. Random variation in association creates a nonuniform "fluorescent speckle" pattern. Fluoresce...
