[Histonet] Agar blocks

[Pablo Sánchez Quinteiro]

Dear histonetters, I need your help.

I have several paraformaldehyde fixed brain samples (postnatal mice) to
section in the vibratome. I am afraid I will not have time enough to cut
them today. Could you tell me the best way to keep this agar blocks until
Monday? By the way, is there any chance to undo agar-agar blocks without
damaging the tissue?

Thanks a lot

Pablo Sanchez
