"WebSpectral Overlap. Spectral overlap refers to the phenomenon when a fluorochromes exhibits fluorescence that “spills over” into a detector channel where it is not expected to show up. This occurs because most fluorochromes have very broad emission spectra. If you are not familiar with this concept, take a look at the fictional example below: " - Emission spectrum flow cytometry

WebThis Is How Full Spectrum Cytometry Works. The process of fluorescence starts with a photon of light, which causes the excitation of a compound that releases the absorbed energy by emitting a photon of light. This process is very rapid (typically occurring in nanoseconds), and the emitted photon is of higher wavelength (thus lower energy) than ... WebPE-Cy7 is a tandem fluorochrome composed of R-phycoerythrin (PE), which is excited by 488-nm light and serves as an energy donor, coupled to the cyanine dye Cy7, which acts as an energy acceptor and fluoresces maximally at 780 nm. PE-Cy7 tandem fluorochrome emission is collected in a detector for fluorescence wavelengths of 750 nm and higher.
