I received samples that have been fixed   in a   1%glut / 20% isopropyl
alcohol solution for paraffin processing. I have never heard of this
fixative, I know alcoholic formalin but never alcoholic glutaraldehyde.
Are any of you familiar with this fixative?
Thank you.

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...
