Movat’s Modified Pentachrome Protocol

Advertisements

This is a quick version of Movat’s Pentachrome.  The long version is an overnight stain, I hate waiting till the next day to find out if the stain worked.  It is sometimes hard to visualize all 5 colors but with a aorta in the heart, it is possible.  The stain picture will have to be edited in later.

Control tissue that I use: Skin, Aorta in the heart

Safety equipment: Work under a hood with lab coat, gloves, and glasses.

  1. Deparaffinize and hydrate to DH2O
