[Histonet] A nit to pick - background IHC staining

[Patsy Ruegg]

The MOM kits may minimize this but they do not eliminate the non specific
binding completely in my experience, macrophages and plasma cells are
particularly difficult to eliminate staining in.

Happy Friday to you all!

I just wanted to comment on the idea that when detecting mouse antibodies on
mouse tissues gives you background staining. I consider background staining
to be non-specific binding of some reagent to the tissue that is then
detected with the chromogen or fluorophore. Anti-mouse antibodies
specifically bind to the mouse Igs in the tissue as well as to the mouse Ig
labeled antigen from the antibody.

It's a nuisance and not specific to your target, but I don't consider it
background. As previously mentioned, mouse on mouse kits work well to
minimize this.
