Re: Compensation for Green contaminating RED channel

Hi Gayle,

What kind of machine do you have?  If it's a B-D one, there probably isn't
a direct FL3-%FL1 compensation circuit.  You'll need to compensate through
the FL2-%FL1 and FL3-%FL2, ie compensate so that the signal is removed from
FL2 first, then compensate FL3 against FL2 until it disappears from FL3 as
well.  If you're not using an FL2 reagent you might be able to skip the
first step.
