Cell membrane staining

[Desok Kim]

Dear Fellow Colleagues,
We are trying to quantify the staining density of some steroid receptors per 
cell using fluorescence microscopy. We have some slides of 8-16 micron thick 
prostate cancer tissue cut from originally frozen tissue block.
We are going to use FITC conjugated secondary antibody to stain steroid 
receptors. 
Here we wonder whether some cell membrame stains such as 
Texas Red conjugated Concanavalin or CellTracker CM-DiI (Molecular Probes) 
will stain cell membrane bright enough to isolate each cell during
image analysis. In our slides, there would be only strips of cut cell membrane
to be stained.
Anyone have some experience similar to what I describe here?
Any suggestions would be appreciated!
