Dear flowers!
We want to analyze marine bacterial populations using flowcytometry.
Because we are new in this field, there are a lot of problems. One problem
occurs, when putting the PMs to about 500 (which is 50% of maximum - and
necessary! for stained bacteria) we get (more or less) huge clouds of
signals even with (particle-free) 0.2 µ filtered A. dest. Shall we filter
the sheath-fluid again (we use BD sheath fluid). Is it electronic noise?
Does anybody have an idea?
