Total 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 کاملTotal internal reflection fluorescence (TIRF) microscopy. I. Modelling cell contact region fluorescence.
Total Internal Reflection Fluorescence (TIRF) is a powerful technique for visualizing focal and close contacts between the cell and the surface. Practical application of TIRF has been hampered by the lack of straightforward methods to calculate separation distances. The characteristic matrix theory of thin dielectric films was used to develop simple exponential approximations for the fluorescen...
متن کاملSingle-shot super-resolution total internal reflection fluorescence microscopy
20 We demonstrate a simple method for combining instant structured illumination microscopy (SIM) 21 with total internal reflection fluorescence microscopy (TIRF), doubling the spatial resolution of TIRF 22 (down to 115 +/13 nm) and enabling imaging frame rates up to 100 Hz over hundreds of time points. 23 We apply instant TIRF-SIM to multiple live samples, achieving rapid, high contrast super-r...
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 کاملIdentification of novel insulin mimetic drugs by quantitative total internal reflection fluorescence (TIRF) microscopy
BACKGROUND AND PURPOSE Insulin stimulates the transport of glucose in target tissues by triggering the translocation of glucose transporter 4 (GLUT4) to the plasma membrane. Resistance to insulin, the major abnormality in type 2 diabetes, results in a decreased GLUT4 translocation efficiency. Thus, special attention is being paid to search for compounds that are able to enhance this translocati...
