Hi Curtis,
thanks for your answer. Actually I also use to stain with DAPI for cell cycle measurements and to measure the signal with a UV lamp. The point is slightly different. I see this constant drift of the signal even when I only measured beads, which are stable for definition.
I think there is a problem hidden somewhere in the machine, but I don't know how to find it, and so I'm asking around...hopefully (for me!) someone already experienced this nasty problem!
