Diphenyl Blue

Fluorescent Dye

4°C (Powder, sealed storage, away from moisture and light)

Diphenyl Blue (Trypan Blue) is a cell active dye, the most commonly used dye for the identification of dead cells, of en used to test cell membrane integrity and cell viability. Diphenyl Blue staining is one of the methods for tissue and cell culture. When cells are deactivated or have incomplete cell membranes, Diphenyl Blue can stain them Blue. Normal living cells with intact cell membranes reject Diphenyl blue and do not stain them blue. However, macrophages are capable of phagocytosis of Diphenyl Blue, so it can be used as a living stain for macrophages[1].
