WebPE-Cy™5 Streptavidin. Fluorescence emission spectra of R-Phycoerythrin and PE-Cy5. Excitation is at 488 nm and the emission spectra are normalized to the absorbance of both dyes at 488 nm. PE-Cy5 has a peak emission spectrum at 669 nm where there is little overlap with the R-PE spectrum. This reduces compensation required to less than 10%. WebThe BD Spectrum Viewer is a tool that depicts the excitation and emission curves of fluorochromes common to flow cytometry. This tool can be used to determine appropriate filters to detect a fluorochrome as well as fluorochrome compatibility and fluorescent spillover. Unlike a static image showing excitation and emission histograms, this tool ...
