Hi Amy,
             We have done immuno's on Pap stained slides before and also use
the Nexes.
To destain ;
Place slide in 1% acid alcohol for  3 minutes ( after you have removed the
mounting media/coverslip  via Xylene/Alcohol and to water.)
Rinse in water
The cytology specimen does not need any pre-treatment as it hasn't been
fixed in Formaldehyde, so it can be placed onto the Nexes.
We sometimes use a Cytology fluid as control, if you haven't a fluid as
control use the control slides as for Paraffin but these will require
pre-treatment.
We usually get good results for diagnosis by the above method.
