Product Description:
Cresol Red is widely used as a pH indicator in various laboratory applications. It is particularly effective in the pH range of 7.2 to 8.8, where it transitions from yellow to red. This makes it a valuable tool in biochemistry and molecular biology for monitoring pH changes in solutions, such as in cell culture media or enzymatic reactions. Additionally, Cresol Red is employed in electrophoresis as a tracking dye to monitor the progress of DNA or protein migration. Its ability to change color with pH also makes it useful in titrations and in assessing the acidity or alkalinity of environmental samples, such as water or soil. In microbiology, it can be added to growth media to visually indicate pH shifts caused by microbial activity.
