I am looking for controls slides for IHC on animal tissues, mainly rat and 
mouse.
Does anyone have extra blocks or slides that they would like to share or  is 
there 
a reliable source to purchase such controls? I am currently trying to titer 
amyloid antibodies for Alzheimer's.  I would also appreciate any hints, 
protocol or procedures that anyone with experience working on animal tissues 
may want to share.
 Thanks in advance.
