RE: Negative control on IHC's

From:"Morken, Tim" <>

It's good practice to run a negative control on each block to test for
non-specific staining. If you are running more than one antibody from the
same animal species you can use each as a negative control for the other.

Is there a good reason to run a negative control on every block when
staining IHC's?  We do a lot of keratin stains on lymph nodes from the
same specimen (not part A, part B, etc.) and we run a negative control
along with the keratin on every block.
