Dyes used in fluorescence microscopy
WebApr 12, 2024 · Fluorescent dyes, also known as fluorophores or fluorochromes, are molecules that absorb excitation light at a given wavelength (generally UV), and after a short delay emit light at a longer wavelength. The delay between absorption and … WebApr 12, 2024 · Wide-field single-photon avalanche diode (SPAD) arrays have gained popularity both in TCSPC ( 12) and time-gated operation ( 13, 14 ). Wide-field FLIM systems have also been shown that utilize microchannel-plate gated optical intensifiers in addition to arrayed PMT detectors ( 15) or charge-coupled device (CCD) cameras ( 16, 17 ).

WebApr 13, 2024 · The dyes were decorated with a HaloTag TM amine (O2) ligand 8 and applied for labeling the HaloTag – vimentin fusion in a stable cell line (live cells). 9 Fluorescence microscopy – confocal and STED – was used for evaluation of the labeling specificity and imaging performance of dye conjugates in live and fixed cells. WebThe fluorescence output of a given dye depends on the efficiency with which it absorbs and emits photons, and its ability to undergo repeated excitation/emission cycles. Absorption and emission efficiencies are most usefully quantified in terms of the molar extinction coefficient (EC) for absorption and the quantum yield (QY) for fluorescence.
