Frequently Asked Questions

Are tissues collected from a USDA-inspected abattoir?

Yes, our rabbit tissues are collected from our Rogers, AR rabbit processing facility, where a USDA inspector remains on site at all times during processing. Each rabbit processed is inspected and any by-products collected are discarded should any animal be found to be unfit for human consumption or otherwise unsuitable for use.

What is the difference between item 41110 and 41170 rabbit brain acetone powders?

Each of these rabbit brain acetone powders begins with a frozen rabbit brain as the raw material prior to acetone drying and powder production. Code 41170 includes barium sulfate during processing while code 41110 does not. Barium sulfate acts to bind clotting factors which may speed coagulation, thus code 41170 has increased sensitivity to clotting deficiencies.

Do you offer products collected from diseased humans or animals?

Not at this time. Please contact us if you are interested in a particular product as we work with a network of suppliers and may be able to find a solution for you.
