Applications :
pH Indicator: Bromophenol Red Sodium Salt is widely used as a pH indicator due to its pH-sensitive color change. It transitions from yellow in acidic solutions to red in alkaline solutions. The transition range typically lies between pH 5.2 and 6.8. It is commonly employed in laboratory settings to monitor pH changes in chemical reactions or to determine the acidity or alkalinity of various solutions.Cell Culture: Bromophenol Red Sodium Salt can be used as a pH indicator in cell culture media. It is added to the culture medium to monitor the pH of the environment in which cells are grown. Changes in the color of the indicator can help assess the pH status of the culture and ensure optimal conditions for cell growth and viability.Gel Electrophoresis: Bromophenol Red Sodium Salt is often used as a tracking dye in gel electrophoresis, particularly in nucleic acid (DNA or RNA) electrophoresis. It migrates through the gel alongside the nucleic acids and provides a visible front that indicates the migration distance. This helps researchers track the progress of the electrophoretic separation.Stain for Protein Detection: Bromophenol Red Sodium Salt can be used as a staining agent for protein detection in polyacrylamide gel electrophoresis (PAGE) and protein assays. It binds to proteins, allowing their visualization and detection. Staining protein bands with bromophenol red helps analyze the presence, quantity, and migration pattern of proteins in biological samples.Microbiology: Bromophenol Red Sodium Salt can be incorporated into specific growth media in microbiology to detect pH changes resulting from microbial metabolic activities. It helps differentiate bacteria based on their ability to ferment carbohydrates and produce acid. The color change of the indicator aids in the identification of different bacterial species.Education and Research: Bromophenol Red Sodium Salt is often used in educational laboratories and research settings to teach and study pH concepts, molecular biology techniques, and protein analysis methods. Its distinct color change and ease of use make it a valuable tool for demonstrating scientific principles and conducting experiments.
