RNAse and membrane staining

Hi all,
We have a problem with fitc/apc/PI stained mouse cells and Rnase to study
membrane molecules and cell cycle.
Mouse cells are stained with moab's. We are using ethanol or PFA as fixation
and  RNAse/PI treatment 30min at 37ºC  prior to facs analysis.
Several times we have seen that membrane staining is affected after RNAse
treatment.
We highly suspect the RNAse solution because 30min. 37ºC without Rnase
doesn't harm the staining.
Is there anyone with comments on this issue?
