Dear Arnold Red670 is, of course, a PE-Cy5 tandem like our Tri-Color or Pharmingen's CyChrome. If Sunnyvale Red is a single dye exciting at 488 and emitting at 670, it would be like B-D's PerCP. It would be great if a good alternative existed. We would certainly be interested Regards Bob Johnson Caltag Arnold Pizzey wrote: > At 10:53 02/06/00 -0700, you wrote: > > > >Hi all, > > > >Our HTS department recently gave a presentation where they described as > >assay system using a fluorochrome named Sunnyvale Red.
