Chemical. CAS 553-24-2. Formula C15H17CIN4. MW 288.78. Neutral red acts as a cellular pH indicator, changing from red to yellow between pH 6.8 and 8.0. More important, it is a dye used for staining in histology. It stains lysosomes red and is used as a general stain in histology, as a counterstain in combination with other dyes, and for many staining methods. It is applied in histology for nuclear staining, fluorescence staining, polychrome staining or for counter staining in Gram staining. It 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. In microbiology, it is used in the MacConkey agar to differentiate bacteria for lactose fermentation. Neutral red is often used as a vital stain. Live cells incorporate neutral red into their lysosomes. As cells begin to die, their ability to incorporate neutral red diminishes.
