Blue/Purple Diaphonized Pinky Mouse

I am delightfully surprised by the clarity of this specimen.

This process, also known as “Clearing and Staining” (clearing, or rendering the tissue translucent, and staining the bones a color), is achieved by bathing the specimen in Trypsin (an enzyme found in the small intestine of vertebrates, which starts the digestion of proteins), and then staining the bones and cartilage with various dyes.
