Daily Compensation in Clinical Flow Lab

Sorry to say that the laws of physics haven't changed that much in
the past 8 years...

Even "daily" compensation is quite possibly too infrequent.  You
should make sure that your compensation controls are valid for every
experiment that you do--and that may not be the case all day long.
Different lots of Cy5PE (or other tandems, such as ECD, Cy7PE) will
require separate compensation settings.  And, since PE tandems
(Cy5PE, etc) change emission properties upon exposure to light, you
have to be careful that the compensation controls are stained in a
very similar way.
