[Histonet] Urea and nitric acid

[Cheryl Crowder]

Hi - For those of you who decalcify a lot.   I have a graduate student who 
want to decalcify temporal bone from a dog using a protocol that uses 5% 
nitric acid and urea.   The urea is supposed to clear the nitric acid color. 
 Our question is - is there a specific urea what should be used.   Having 
never used it myself, I have no idea what to buy.
