Neutral Red is most commonly used for histological stain for lysosymes but has also been incorporated in investigation of viruses, as a pH indicator, determination of DNA with optical and electrochemical methods, evalutaion of synthetic and naturally derived biomaterials. Neutral red can be electrochemically polymerized and used as a redox mediator. The compound once taken up by cells can be used to acertain cell viability with a excitation maximum at 470 nm and emission maximum at 580nm.
