Go to http://stainsfile.info/StainsFile/stain/cell/aldtolblue.htm for a 
reliable method. It still uses toluidine blue, but the staining is not 
based on metachromasia and mast cell granules are dark blue. Most 
toluidine blue samples will work, but occasionally one doesn't. Fisher 
brand is OK as are many others.

I used to use a section from an acute appendicitis case as the control.
