BD ® Spectrum Viewer is an interactive, online tool to support flow cytometry fluorochrome comparison and selection. The tool enables you to: Analyze and compare excitation (Ex) and emission (Em) spectra of a broad library of dyes; Detect spillover and optimize fluorochrome selection for your instrument configuration/filters setup; Toggle between Combined Ex/Em Graph view or Stacked Ex/Em Graphs view for easier visibility between spectra; Visualize and analyze emission profiles on any standard flow cytometer or use the BD FACSymphony ™ A5 SE Spectral Cell Analyzer and access similarity and complexity indexes; Visualize peak intensities of spectral signatures in a unique heatmap, which is especially helpful when looking at large fluorochrome combinations; Save, export and/or share your panel
