Bromphenol blue is a pH indicator that changes color depending on the acidity or alkalinity of a solution. In a more acidic environment (pH below 3.0), it appears yellow, while in neutral to alkaline conditions (pH above 4.6), it transitions to blue. This property makes it useful in various laboratory applications, including as a tracking dye in gel electrophoresis, where it helps visualize the migration of molecules based on their size and charge. Additionally, it can be used as a staining agent in biochemical assays.

What is th blue dye added to the sample before the electrophoresis is performed?
In biochemistry labs, the traditional answer for a protein gel (polacrylamide gel electrophoresis) is bromphenol blue. For a DNA gel (agarose gel electrophoresis), traditionally the same dark blue dye bromphenol blue was combined with the lighter, slower migrating blue dye xylene cyanol. Oftentimes nowwe only use the bromphenol blue, or even substitute for it with Orange G, which is a UV-transparent dye that more easily enables the visualization of smaller molecular weight nucleic acids that migrate in the same region.

What happens if you mix bromphenol blue and NaOH?
When bromophenol blue is mixed with NaOH, the solution turns blue because the pH becomes alkaline. Bromophenol blue is a pH indicator that changes color in different pH ranges. In the presence of NaOH, which is a base, the bromophenol blue changes from yellow (at acidic pH) to blue (at alkaline pH).
