Dear Pam,
I've had the same problem.  I called Richard-Allen just after they were
"absorbed" by Thermo Fisher and got no answers.  They had never heard of
such a problem and didn't know how to solve it.  I have heard from another
user that had the same exact problem.  I lost precious samples, E6.5 mouse
embryos, because of this "drying out and hardening" of the histogel.  I had
to stop using it all together.
If anyone has any suggestions, please let us know!
Take care Pam and all histonetters,
Jo Dee

Dear Group: I'm having problems with the processing of small tissues in
histogel. I follow the suggested embedding directions on the package and
then process the gel blocks.  The results are very inconsistent-ideally,
I'll get nice soft gel blocks-but, usually in a batch of 10 I get 2 good
blocks and 8 dried up, flat hard squares.  They are all handled and
processed the same.  Anyone experience this before?  Thanks for any input.
