Thermo Scientific Chemicals Neutral Red, ACS

Description

Nuclear counterstain useful in pH range 6.8 to 8.0 | CAS: 553-24-2 | C15H17ClN4 | 288.779 g/mol

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, evaluation 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. It is used as a red nuclear counter stain in various cytochemical procedures. It is suitable for microscopy and microbiology and supravital staining of living blood cells. A vital dye used as an indicator and biological stain.
