[Histonet] Re: Buffer.

Re this thread on buffering: cacodylate buffering is frequently used
with glutaraldehyde for electron microscopy. Nobody ever seems to
mention it, but cacodylate (cacodylic acid) contains organic arsenic,
and is extremely toxic. See

http://en.wikipedia.org/wiki/Cacodylate

What precautions are advisable in handling it? Is it permitted in a
hospital laboratory?

I've been reading about a procedure that may require it - will post
more information if I receive it from the author.
