Transient state monitoring by total internal reflection fluorescence microscopy.
Triplet, photo-oxidized and other photoinduced, long-lived states of fluorophores are sensitive to the local environment and thus attractive for microenvironmental imaging purposes. In this work, we introduce an approach where these states are monitored in a total internal reflection (TIR) fluorescence microscope, via the characteristic variations of the time-averaged fluorescence occurring in ...
متن کاملTotal internal reflection fluorescence (TIRF) microscopy.
Total internal reflection fluorescence (TIRF) microscopy (TIRFM) is an elegant optical technique that provides for the excitation of fluorophores in an extremely thin axial region ("optical section"). The method is based on the principle that when excitation light is totally internally reflected in a transparent solid (e.g., coverglass) at its interface with liquid, an electromagnetic field, ca...
متن کاملTopic Introduction Total Internal Reflection Fluorescence Microscopy
The goal in fluorescence microscopy is to detect the signal of fluorescently labeled molecules with great sensitivity and minimal background noise. In epifluorescence microscopy, it is difficult to observe weak signals along the optical axis, owing to the overpowering signal from the out-of-focus particles. Confocal microscopy uses a small pinhole to produce thin optical sections ( 500 nm), but...
متن کاملA Thin Layer Imaging with the Total Internal Reflection Fluorescence Microscopy
Total internal reflection fluorescence microscopy (TIRFM) is an optical technique that allows imaging of a thin layer of the sample with a thickness of about 100-200 nm. It is used in science of cell biology to study cellular processes, especially near the membranes of living cells. This method is based on the total internal reflection phenomenon, where the evanescent wave is generated in the l...
متن کاملReal-time monitoring of NKCC2 endocytosis by total internal reflection fluorescence (TIRF) microscopy.
The apical Na-K-2Cl cotransporter (NKCC2) mediates NaCl reabsorption by the thick ascending limb (TAL). The amount of NKCC2 at the apical membrane of TAL cells is determined by exocytic delivery, recycling, and endocytosis. Surface biotinylation allows measurement of NKCC2 endocytosis, but it has low time resolution and does not allow imaging of the dynamic process of endocytosis. We hypothesiz...
