Alamar Blue is a fluorescent dye commonly used in scientific research to assess cell viability and proliferation. It is non-toxic and can be used in live cell assays, making it a popular choice in laboratories. When cells are alive and metabolically active, they convert Alamar Blue from a blue, non-fluorescent form to a pink, fluorescent form, allowing researchers to measure cell health. This dye is often utilized in various fields, including cancer research, drug development, and toxicology studies. Its ease of use and reliable results make Alamar Blue a valuable tool for scientists studying cellular responses to different treatments or conditions.
