Jesus,
If the biopsy is unreadable, there is nothing to lose to
follow Carole's suggestion. Obviously you'll have to melt the paraffin block 
and the specimen first, remove the wax with xylene and bring it through to a 
low cocentration alcohol (50%) before putting it in the sodium carbonate 
solution.

Good luck!
