General description

Neutral Red is a cationic dye that is used for nuclear counterstaining in biological research. It also serves as a pH indicator in analytical laboratories. On decomposition, neutral red dye releases carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxides, and hydrogen chlorides. Therefore, this dye is considered toxic and is recommended to remove before discharge into receiving streams.

Application

Neutral Red Solution (0.33%) has been to stain viable cells and measure cell viability. It has also been used as a component of culture medium for enzymatic digestion of ovarian medulla tissue to extract follicles.
