RE: [Histonet] gliut/isopropyl alcohol

From:"Molinari, Betsy"

Hi Bob,
Thanks for your input. I may ask a couple of the surgery staff here if
they are familiar with that technique. A point of interest, these are
valves. I loaded them last night starting in 70% ETOH, I am curious to
see how they turned out and how much effect it will have on the B&B and
PTAH I will be running on them
Thanks again,

Hi Betsy,
Is the specimen perhaps a heart valve made from pig tissue??
The only time I've heard of alcoholic glutaraldehyde is for pretreating
pig valves before they're implanted in humans.  There's some kind of
relationship between alcohol and glut, and preventing calcification of
the valve.  Can't remember the details right now, but you have to treat
the valve with one of those reagents before using the other.
Just a thought...
