Description

General description

Well developed granules of volutin (polyphosphate) may be seen in unstained wet preparations as round refractive bodies within the bacterial cytoplasm. With basic dye, they tend to stain more strongly than the rest of the bacterium, and with methylene blue solution (Cat. No. 01363) they stain metachromatically, a reddish purple color.

Application

Neutral Red, a histological vital stain, is used as a stain and counterstain. It is used to stain Golgi apparatus in cells and Nissi granules in neurons. As a pH sensitive dye, neutral red stains lysosomes red within cells.
