Molecular Probes sells polystyrene beads that are excited at 488 nm and emit at 605 nm or even at 645 nm. Either one should work if you want something that can be detected in Fl3. Thanks --------------------------------------------------------- Joerg Hildmann wrote: Hello, I'm using the POLYSCIENCES fluoresbrite YG beads detected in the FITC- channel of a three fluorescence FASCSCAN. Now I need particles which absorb near 488nm and have a fluorescence about 605nm but hardly touch the FITC and PE fluorescence for three colour staining. Who has an idea because POLYSCIENCES themselves has no further information than main excitation and emission values. Thanks for any help Joerg Hildmann. ---------------------------------------------- Mahesh K. Bhalgat, Ph.D. Molecular Probes, Inc.
