Nanometer-localized multiple single-molecule fluorescence microscopy.
Fitting the image of a single molecule to the point spread function of an optical system greatly improves the precision with which single molecules can be located. Centroid localization with nanometer precision has been achieved when a sufficient number of photons are collected. However, if multiple single molecules reside within a diffraction-limited spot, this localization approach does not w...
متن کاملSingle Molecule Fluorescence Microscopy on Planar Supported Bilayers
In the course of a single decade single molecule microscopy has changed from being a secluded domain shared merely by physicists with a strong background in optics and laser physics to a discipline that is now enjoying vivid attention by life-scientists of all venues (1). This is because single molecule imaging has the unique potential to reveal protein behavior in situ in living cells and unco...
متن کاملChallenges in quantitative single molecule localization microscopy.
Single molecule localization microscopy (SMLM), which can provide up to an order of magnitude improvement in spatial resolution over conventional fluorescence microscopy, has the potential to be a highly useful tool for quantitative biological experiments. It has already been used for this purpose in varied fields in biology, ranging from molecular biology to neuroscience. In this review articl...
متن کاملQuantitative Aspects of Single Molecule Microscopy.
Single molecule microscopy is a relatively new optical microscopy technique that allows the detection of individual molecules such as proteins in a cellular context. This technique has generated significant interest among biologists, biophysicists and biochemists, as it holds the promise to provide novel insights into subcellular processes and structures that otherwise cannot be gained through ...
متن کاملAlternative spliceosome assembly pathways revealed by single-molecule fluorescence microscopy.
Removal of introns from nascent transcripts (pre-mRNAs) by the spliceosome is an essential step in eukaryotic gene expression. Previous studies have suggested that the earliest steps in spliceosome assembly in yeast are highly ordered and the stable recruitment of U1 small nuclear ribonucleoprotein particle (snRNP) to the 5' splice site necessarily precedes recruitment of U2 snRNP to the branch...
