Subject: Best fixative for LCM


I have been asked by another researcher here to posat this.  What have
people doing LCM found was the best fixative for capturing cells. 
Currently our material is formalin-fixed and paraffin-embedded (using
archived tissues).  We are going to be recieving some new tissue and
will need to paraffin-embed it, however we are wondering what the best
fixative would be-formalin, Carnoy's, alcohol?- keeping in mind that we
also need good morphology.

Thanks for any and all suggestions.
