It is actually a good idea to test the binding of the second business end of your antibody in a different species. It was probably one of the key failures of the TGN1412 trial not to recognise that the different processing of the Fc end is a monkey business. They should really have noticed as they knew their in vitro experiments did not work if they used a Fab2
Guess you already picked up
I would try directly labelling of the IgG2b with any of the commercially available kits. The advantage of that approach is that you can directly measure the binding affinity difference between human and monkey in situ using your flow cytometer even with your dedicated reagent. In addition you should look at their effect as immune-complexes and also make sure you remove them.

Subject: [Cytometry] Anti human IgG2b secondary
We are trying to identify binding of a human IgG2b antibody binding on Rhesus macaque monocytes. I wonder if anyone could suggest a secondary that would recognize the human, but not the macaque antibodies.
