I am currently working with PVA using the physical polymerization method, of multiple freezing/thawing (F/T) cycles. Since I've been getting opposite opinions regarding this question, I wanted to hear your intake on the matter:
If, for example, I need to run 4 x F/T cycles (18hr / 6hr, respectively), but I started the protocol just before the weekend. Is it better to leave the samples during the weekend on FREEZING or on the THAWING?
And if you can, please explain your recommendation.
Thanks a lot
