Staining - Stainability of Tissues

Stainability of Tissues

Tissues which take up stains are called chromatic. Chromosomes were so named because of their ability to absorb a violet stain.

Positive affinity for a specific stain may be designated by the suffix -philic. For example, tissues that stain with an azure stain may be referred to as azurophilic. This may also be used for more generalized staining properties, such as acidophilic for tissues that stain by acidic stains (most notably eosin), basophilic when staining in basic dyes, and amphophilic when staining with either acid or basic dyes. In contrast, Chromophobic tissues do not take up coloured dye readily.
