Phenol Red is a pH indicator reagent commonly used in culture media as a convenient means to check cell and tissue health. Its color gradually shifts from yellow (around pH 6) to red (around pH 8) to bright pink (over pH 8.2). This indicator allows observation of cell culture pH change that can arise from dying cells, overgrowth of contaminating bacteria, and accumulation of waste products. Phenol Red is also known as phenolsulfonphthalein and appears as red crystals in its solid form.
