Ehrlich Hematoxylin - IHC Counterstain Applications

Ammonium alum-ripened hematoxylin achieves intense nuclear staining requiring differentiation across antibody localization and tumor grading workflows.

Immunohistochemistry laboratories provide crisp nuclear counterstain preventing IHC misinterpretation. Regressive protocol reveals nucleolar detail across proliferation marker assessment.

Quality control verifies ripened hematoxylin oxidation, mordant stability, and chromatin selectivity. Glycerin-alcohol formulation prevents precipitation artifacts.
