description Product Description
Used as a pH indicator in various laboratory applications, particularly in microbiology and biochemistry. It helps in determining the pH range of solutions, typically changing color from yellow to red between pH 5.2 and 6.8. Commonly employed in cell culture media to monitor pH changes, ensuring optimal conditions for cell growth. Also utilized in electrophoresis and titration experiments to visualize pH shifts. In addition, it serves as a tracking dye in agarose gel electrophoresis to monitor the progress of DNA or RNA migration. Its color-changing property makes it a valuable tool in analytical chemistry for detecting endpoint reactions.
