What Are Some Common Stains Used in Histology That Rely on Adsorption?
Several histological stains depend on the principle of adsorption to effectively highlight cellular components: - Hematoxylin: Commonly used to stain cell nuclei blue. Its adsorption is pH-dependent, often requiring a mordant to enhance attachment. - Eosin: Stains cytoplasmic components pink and works well in an acidic environment, relying on weak ionic interactions for adsorption. - Periodic Acid-Schiff (PAS): Stains carbohydrates and glycogen a magenta color. This stain involves a specific chemical reaction followed by adsorption.
