You can add brain to that list.  A possible reference is , Appl. Immunohistochem: issue 5, 1997.  I have swithced to a non-biotin amplification kit from Zymed.

	Does anyone out there have a good reference or list of tissues containing endogenous biotin?  We don't like to put avidin biotin block on our staining procedures unless the tissue requires it.  We're aware of liver and kidney but there are other tissue types that also contain biotin to a lesser degree.  Thanks for your help.
