HI Sharon:

1. Crystal violet does not enjoy wide use in pathology. However, you can 
use it any way you want.
2. Toluidine blue is a good Nissl stain but cresyl violet is more common.
3. Cresyl violet is more common, I suppose most prefer the violet color 
to blue. Cresyl violet gives better contrast with Luxol fast blue and I 
think cresyl violet is easier to differentiate with alcohols.
4. Probably.

Geoff

Are getting crystal violet and cresyl violet confused?
