Texas Red  The excitation spectrum and emission spectra (bold
line) are shown for Texas Red. The red-shaded region represents
the bandpass filter commonly used to measure TR fluorescence. On
most flow cytometers, TR is excited either by a Dye Laser (tuned
to 595-605 nm) or a Krypton laser (567 nm). Compare the TR
fluorescence spectra to spectra for several FACS
immunofluorescence dyes.
