[Histonet] Eosin Leaching

[Adrienne Anderson]

We haven’t changed our mounting medium, but I’ll have to check on the alcohol levels. When I stain (we hand stain only - very small lab), I always make sure the alcohol is higher than the eosin, but I have a lab assistant now, and it’s very possible I didn’t make that a point. I’ll try that.

Any more tips are welcome still - thank you all!
