Should the claim, "... a 24 hour 'turnaround' to 
fully decalcify a Mouse Head completely & doesn't 
interfere in Immuno" be believed? Immuno for
every antigen? If it decalcifies things rapidly 
it is almost certainly a quite concentrated acid,
and may cause chemical changes such as Feulgen
hydrolysis of DNA and extraction of RNA. Is the
product's composition disclosed, or is it a
secret brew? It's extremely easy to make 
decalcifying solutions in the lab from simple,
inexpensive ingredients, following well tried
and understood published recipes.
