Hi - Has anyone tried looking at chromosomes on a benchtop instrument? We are looking at muntjak cells (with only 3 chromosomes) stained with PI. We have tried on our new BD LSR but seemed to have significant fluorescence "noise" when increasing the FSC detector to max. Is the 15mW laser just too weak to be able to detect them? Suggestions?
