Staining is the process by which a substance like a tissue or a polymer is coloured to some contrasting colour by means of adding different chemicals, which makes it easier to study at cellular level.

Stains include:

1. Leishman stain – it is eosinated methylene blue in acetone-free methyl alcohol. Eosin is acidic part of the stain which reacts with basic part and methylene blue is basic part that reacts with acidic part.
2. Gram stain – it is staining of acid-fast bacteria with methyl violet, also called gentian violet. This is a basic dye, which reacts with acidic bacteria to give a blue colour.
