Jorge I can comment on the cresyl etch violet - we actually purchased cresyl violet acetate from MP Biomedicals. This particular chemical has not been certified by the biological stain commission, if you are looking for a dye that has been certified then I would go to Sigma-Aldrich - they also supply this chemical.

Good customer service and affordable prices a must. In both cases, do you know if these stains work on tissues preserved in ethanol (70%), some of the tissues could have been preserved for years.
