[Histonet] MMA Embedding


I am trying to embed a polymer in MMA.  The protocol I am using has me
dehydrating the samples at 4C and then putting it into MMA for 1 week at
-20C.  The next week I am supposed to add BPO to the MMA and also keep it
at -20C.  When I looked at it the BPO is crystalizing out.  Is this okay?
Does anyone else embed at such a low temperature?  We usually do it at 37C
in a water bath.  They want these particular samples done this way.  Any
advice for success would be greatly appreciated.

Thank you,
