[Histonet] Multi-specimen tissue micro array on the cheap

[O'Donnell, Bill]

To all who responded to my last post concerning an inexpensive method to make micro arrays: 

I will be more than happy to share, once I actually get around to writing it up. Now I have the impetus to do so.

I'll get it done in the next week and will post in general to this list-serve.

Subject: Re: [Histonet] Advice on fatty liver sectioning

-18˚ is the temp I use when I section liver for ORO and I usually cut the sections at 5 microns. It sounds like your tissue was not frozen correctly.
