Trypan Blue Staining Solution (ab233465)

Trypan Blue Staining Solution (ab233465) is a vital stain that colors dead tissues or cells blue. Since cells are very selective, in a viable cell, the trypan blue will not pass through the membrane; however, it traverses the membrane in a dead cell. Hence, dead cells are shown as a distinctive blue color under a microscope. The method cannot distinguish between necrotic and apoptotic cells.
