CAS 72-57-1: Trypan blue
Description:Trypan blue is a synthetic dye commonly used in biological and medical research, particularly for cell viability assays. It is a diazo dye that appears as a dark blue powder or solution and is soluble in water. The dye selectively penetrates dead cells, allowing researchers to distinguish between viable and non-viable cells under a microscope. This characteristic is due to the compromised membrane integrity of dead cells, which allows the dye to enter, whereas live cells exclude it. Trypan blue is often used in conjunction with hemocytometers for counting cells in culture. While it is generally considered safe for laboratory use, it is important to handle it with care, as it can be a potential irritant and is classified as a possible carcinogen. In addition to its applications in cell biology, Trypan blue has also been used in histology and as a staining agent in various diagnostic procedures. Overall, its ability to provide a visual distinction between live and dead cells makes it a valuable tool in cell biology research.
