Uses of Cresol Red Indicator

1. pH Indicator:
   • Titrations: Cresol Red is often used in acid-base titrations to determine the endpoint of a reaction by indicating a pH change.
   • pH Measurement: It helps in measuring the pH of solutions, especially in the intermediate pH range.
2. Electrophoresis:
   • DNA and RNA Analysis: Cresol Red can be used as a tracking dye in agarose and polyacrylamide gel electrophoresis to monitor the progress of nucleic acid migration.
3. Cell Culture:
   • pH Monitoring: In cell culture media, Cresol Red helps in monitoring the pH changes, which is crucial for maintaining optimal conditions for cell growth.
4. Biochemical Assays:
   • Enzyme Activity: It is used in various biochemical assays where pH change is an indicator of enzyme activity or reaction completion.
5. Microbiology:
   • Growth Media: In microbiological media, Cresol Red can indicate changes in pH due to microbial metabolism, aiding in the identification and study of microorganisms.
6. Education and Demonstrations:
   • Teaching Tool: In educational settings, Cresol Red is used to demonstrate acid-base reactions and pH changes in a visual and engaging manner.
