Re: [Histonet] Purple Haze.....
No slide adhesive used, this appears on standard non-charged, non-adhesive coated slides. This artefact is localised to the cell nuclei only.
I know what you mean though, I remember in the old days when we used to albuminise slides, they always had a blue wash over them.
