[Histonet] Counter stain

[Connolly, Brett M]

Lorie,

I've used 0.25% Metanil Yellow and/or Light Green...either one works fine,
just play with the times to get the staining intensity you want.

Subject: [Histonet] Counter stain


I am doing a peroxidase DAB stain for an antigen that is present only in
small quantities in the nucleus. I am doing it on rat bone. If I
counterstain with hematoxylin it covers the DAB stain. What else can I use
that will only stain the cytoplasm and not the nucleus. i thought of methyl
green but it too is supposed to stain the nucleus. I thought of neutral red
but it won't look so good with the brown. Suggestions?
 
Cheers,
Lorie
