RE: cutting whole mice

From:"Georger, Mary"

Good Morning Patsy,
I process mouse embryos as well as organs from adults that have been treated
with beta gal post fixation. My processing protocol is about 5 hours start
to finish, shorter if it is just small organs, no brain tissue. I have had
no loss of signal, and the PI's are happy. If you want the complete run up
let me know and I will forward it on to you.
Have a great day!
