Is the hinged dichroic holder you are using recycled from an old BD
instrument? If so, we tried that too, and failed to get any purple signal
out. The Plus comes with a dichroic holder that is stationary and I rigged
(with cardboard and double backed tape) a way to install my 440 LP onto that
holder. Hey, it works!
We use the Bright Blue Fluorescebrite (sp?) beads from Flow Cytometry
Standards Corp. to align the UV laser and get great signal into both the 485
and 405 PMTs.
