Hi Gary. We used to fix mouse embryos (both pre- and post-implantation) in PFA then methanol. After your standard PFA fix, wash in PBS then pass them through 25%, 50%, 75% then 100% methanol (in PBS, 5mins each step). To rehydrate, just do the reverse: 75%, 50%, 25% then back into PBS. This worked fine for me and others in the lab (the embryos do get a little sticky while in the methanol, though!). Hope this helps
