Quench GFP?
 
I've infected some primary human mammary epithelial cells with an shRNA encoding lentivirus that bicistronically expresses GFP.

I'm labeling these cells with PE, APC, and PE-Cy5 conjugated antibodies. The APC and the PE-Cy5 look great, but the GFP signal is so intense that I can not possibly compensate enough to get a reliable and sensitive reading of the PE signal.

Anyone have any suggestions as to how I might ablate the GFP signal, but preserve the ability to detect the three cell-surface antigens?

Confocal imaging.
