Dear 'netters,
I'm cutting some semi-thin sections (1 micron) from Epon-embedded tissues. 
I'd like to know what people use for mounting slides of toluidine blue
stained tissues. 

I noticed that there was a bleaching of sections after serial passage in
alcol 70%, 95%, 100%, xylene to DPX. Is better to use an aqueous medium (for
example Glycerol gelly )? Are there significant differences in mounting
among epoxidic resins (for example Epon 812 versus Spurr's )?

Thanks in advance

Regards,
