Alkali Scientific Trypan Blue, 25 G

Trypan Blue is a vital dye used to assess cell viability, providing a clear method for distinguishing live cells from dead cells in culture. This 25g container is perfect for labs performing routine cell viability assessments, such as in cytotoxicity assays and microbiological studies. The dye penetrates dead cells but is excluded from living cells, making it an essential tool for quantifying cell health. Trypan Blue is commonly used in cell culture, drug testing, and clinical microbiology to evaluate the impact of various treatments or conditions on cell survival. This dye is a standard reagent in laboratories focused on cell health monitoring and viability analysis.
