WebPhenol red, often found in DMEM, is used to visualize the pH in cell culture dishes. This compound, however, can quench the signal of some visible wavelength fluorescent dyes when used during live cell fluorescent microscopy. Another component of DMEM is riboflavin, which is autofluorescent and can influence the signal-to-noise ratio. WebPhenol red has been used as a pH indicator dye in tissue culture media for decades (Figure 1). While its presence is not critical for maintaining cell cultures, it is often used as a quick means for researchers to check on culture stocks. Most mammalian tissues exist at a near neutral pH.
