Re: [Histonet] IHC together with toluidine blue staining for mast cells

From:Rene J Buesa

IF your antibody is FOR mastcells, you will block the toluidine blue staining sites with the DAB substrate, but IF you are using an Ab for a different target, then you can stain the mast cells with toluidine blue, but that will be "like" a counterstain.

  Hi Histonetters,

I was wondering if anyone knows how to stain paraffin-embedded tissues for a
certain Ab (standard IHC), and use toluidine blue to stain mast cells on the
same section. Is it at all possible? I emphasize that I would like to use
toluidine blue not for counterstaining, but to detect mast cells, and to
still be able to see my IHC staining. Glad to recieve any piece of advice.
