Just to second Mario Roederer's sound comments on isotype controls -- and
the complications of needing to match control concentration with stain
concentration (when we often don't know the concentration of either....).

There is, in addition, the added complication if using directly
conjugated antibodies. For the isotype control to be valid, it would
also have to match the staining antibody with respect to its F/P ratio.
And accurate determination of F/P ratios for antibodies used in flow
cytometry is a huge can of worms.....
