Fluorescent intensity spectrum
WebA fluorescence excitation spectrum is when the emission wavelength is fixed and the excitation monochromator wavelength is scanned. In this way, the spectrum gives information about the wavelengths at which a sample will absorb so as to emit at the single emission wavelength chosen for observation. WebJan 10, 2024 · DAPI fluorescence intensity increases if attached to DNA compared to its unbound state. It is excited by UV-light with a maximum at 358 nm. Emission spectrum is broad and peaks at 461 nm. A weak fluorescence can also be detected for RNA binding. In this case, emission shifts to 500 nm.
