Re: Prefer mold
We make up the concentrate.
As we have been checking our older specimens for mold we have found a
Discoloration in the tissues suggesting a break-down of the Prefer. Have
you seen this? Have you been changing the Prefer on longer-stored
We x-rayed some small pig mandibles and have seen a mottling effect in the
bone. Again, have you experienced this?
I have emailed Anatech. No response yet.

Either way, I would start by contacting ANA-Tech directly; they are great to work with and I am sure they will help you with this problem.
