WebSpectral overlap: When performing multiplex experiments to detect multiple targets in the same sample, refer to fluorophore spectral characteristics, laser wavelengths, and microscope filter ranges. Microscope emission filter configurations should be selected to reduce spectral overlap, but choosing fluorophores that do not have long emission ... Webmultiple reagents, spectral overlap (or spillover) becomes an issue. The more colors you attempt to resolve on any particular cell, the more spillover impacts sensitivity. We use compensation, an adjustment applied to all colors, to correct for spillover. For example, a cell population fluorescing only in FITC will show no PE fluorescence, on WebWhen imaging multiple fluorophores in widefield fluorescence microscopy, bleed-through artifacts can often be overcome by the judicious choice of filter combinations. In addition to considering the emission spectral overlap of fluorophores, cross-excitation due to overlapping absorption bands must also be addressed. bitvise ssh c2s
