WebAug 28, 2024 · 4.4: UV-Visible Spectroscopy. Ultraviolet-visible (UV-vis) spectroscopy is used to obtain the absorbance spectra of a compound in solution or as a solid. What is actually being observed spectroscopically is the absorbance of light energy or electromagnetic radiation, which excites electrons from the ground state to the first … WebSep 1, 2024 · Phenol red, as a source of ROS production in cell culture, has not been thoroughly investigated. PR is widely used in cell culture to observe pH changes, where it would have a yellow colour at a pH of 6.4 or below that changes into red at pH of 8.2 and above. PR has also been used in various protocols to detect hydrogen peroxide (H 2 O 2 ).
