Neutral red indicator is manufactured by Securex Lab Sciences. This dye is commonly used in histological analysis. It is part of several staining protocols. It stains lysosomes of cells with a red colour. Some of the other organelles stained by neutral red include golgi apparatus and the nissil granules in neuronal cells. Further, it is used with Janus Green B to stain the embryonal tissue. The indicator is used in cell biology experiments to differentiate between live and dead cells. The lysosomes of only live cells are stained red. The dead cells fail to absorb neutral red. Neutral red is a pH indicator and it changes colour from red to yellow based on the pH change from 6.8 to 8. It is also incorporated into MacConkey agar for bacterial differentiation. Molecular formula: C15H17N4 Molecular mass: 288.78 g/mol IUPAC name: 3-Amino-7-dimethylamino-2-methylphenazine hydrochloride Neutral red indicator is manufactured by Securex Lab Sciences.
