Extrinsische fluorophore
WebNov 15, 2024 · For the fluorophores used in microscopy, one complete cycle from excitation to the return to ground takes in the region of 0.5 to 20 nanoseconds. Fluorophore excitation and emission wavelengths are commonly abbreviated as the Greek letter lambda with a subscript "ex" (excitation) or "em" (emission; l ex or l em). WebTetrazine is known to efficiently quench the fluorescence of various fluorophores via a mechanism referred to as through-bond energy transfer. Upon light irradiation, restricted tetrazine moieties undergo a photolysis reaction that generates two nitriles and molecular nitrogen, thus restoring the fluorescence of fluorophores.
