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).
Pappenheimer bodies (Peripheral Blood / May-Grünwald Giemsa and Prussian blue stain) Pappenheimer bodies are abnormal basophilic granules of iron found inside red blood cells on routine blood stain. [1] They are a type of inclusion body composed of ferritin aggregates, or mitochondria or phagosomes containing aggregated ferritin. They appear ...
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 .
Bod is a British children's television programme first shown on BBC1 in 1975, with thirteen episodes, based on four original Bod books by Joanne and Michael Cole. [3] It is a cutout animated cartoon series narrated by John Le Mesurier and Maggie Henderson with music by Derek Griffiths and produced by David Yates.
It is a supravital stain. [2] It is closely related to methylene blue, an older stain in wide use. Safety. New methylene blue is toxic. Skin contact or inhalation ...
Reticulocytes appear slightly bluer than other red cells when looked at with the normal Romanowsky stain. Reticulocytes are also relatively large, a characteristic that is described by the mean corpuscular volume. Supravital stain of a smear of human blood from a patient with hemolytic anemia. The reticulocytes are the cells with the dark blue ...
