The term "vital stain" is used by some authors to refer specifically to an intravital stain, and by others interchangeably with a supravital stain, the core concept being that the cell being examined is still alive. As the cells are alive and unfixed, outside the body, supravital stains are temporary in nature. [1] [2]
In supravital staining, living cells have been removed from an organism, whereas intravital staining is done by injecting or otherwise introducing the stain into the body. The term vital stain is used by some authors to refer to an intravital stain, and by others interchangeably with a supravital stain, the core concept being that the cell ...
Heinz body stain of feline blood, showing three distinct Heinz bodies. Heinz bodies appear as small round inclusions within the red cell body, though they are not visible when stained with Romanowsky dyes. They are visualized more clearly with supravital staining [5] [6] (e.g., with new methylene blue, crystal violet or bromocresol green).
Brilliant cresyl blue is a supravital stain used for counting reticulocytes. [2] It is classified as an oxazine dye . N95 dust masks , eye shields, and gloves must all be worn when handling the chemical.
A Ziehl–Neelsen stain is an acid-fast stain used to stain species of Mycobacterium tuberculosis that do not stain with the standard laboratory staining procedures such as Gram staining. This stain is performed through the use of both red coloured carbol fuchsin that stains the bacteria and a counter stain such as methylene blue .

It stains lysosomes red. [1] It is used as a general stain in histology, as a counterstain in combination with other dyes, and for many staining methods. Together with Janus Green B, it is used to stain embryonal tissues and supravital staining of blood. It can be used for staining the Golgi apparatus in cells and Nissl granules in neurons.
