[Coral-List] tissue separation

[Selina Ward]

Dear Muthu
I decalcify using hydrochloric acid and formalin.  I use acid that is made
for use in swimming pools as this is inexpensive. In 1 litre I would use
900ml water, 80ml acid, 20ml formalin.  This is gentle enough to keep
reproductive structures intact and, for small finger sized pieces, takes
about a week with one change of acid. This of course varies according to the
species.

hi muthu
tissue seperation form the skeleton involves
dissolving the calcium....so mild acid will do...
it is also important to know the purpose for the
tissue seperation.
for histology, I decalcify the tissue in 1:1
mixture of 20% citric acid and 50% formic acid...
it works very well for me.....but it takes long
time......it gives best result if you keep for
overnight with changes every 3-4 hours.....
best of luck for ur work
cheers
