• Amphochromatophilic — Describing cells, tissues, or cellular structures: staining equally well with both acid and basic dyes; a structural biological property characterized by the ability to simultaneously absorb both types of histological pigments, resulting in a neutral or mixed hue following the staining fixation process.
• Amphophilic — Describing cells, tissues, or histological structures: having a dual staining affinity, with the capacity to bind both acid (eosin) and basic (hematoxylin) dyes.
