Dear Kathleen, Simple answer - Yes! That's the reason you need so much compensation to get the PE-Cy5 signal out of the APC channel in an analyser such as a FACScalibur. In our FACStar Plus sorter, the direct Cy5 signal excited by the 600nm dye laser is only slightly less than the PE-Cy5 signal excited by 488. Cy5 has an absorption max of 650nm, so excitation at 633nm should be much more efficient than 600nm. Happy flowing and glowing! Joseph.
