You can indeed use Cy3 on a FACScan. We have looked at a dozen or
more in-house conjugates. While Cy3 would *prefer* to be excited at
around 550nm, or even at 515nm, you can still get enough signal using
488nm if the antibody is suitable. Expect up to one decade less signal
than for a comparable PE conjugate.
