Gel electrophoresis is a cornerstone technique in molecular biology, genetics, and biochemistry, enabling the separation of macromolecules like DNA, RNA, and proteins. However, these molecules are often colorless, making it difficult to visually track their movement through the gel matrix during the separation process. This is where tracking dyes, such as Bromophenol Blue, play an indispensable role. NINGBO INNO PHARMCHEM CO.,LTD. understands the importance of these visual aids in achieving successful experimental results.

Bromophenol Blue, with its distinct color and electrochemical properties, is one of the most commonly used tracking dyes in electrophoresis. When mixed with a sample, it migrates through the gel alongside the target molecules. Its migration rate is influenced by factors like gel concentration, buffer composition, and voltage, but generally, it serves as a reliable visual indicator of the run's progress. For instance, in a typical 1% agarose gel, Bromophenol Blue migrates at a rate roughly equivalent to a DNA fragment of about 300 base pairs. This allows researchers to gauge how far their sample has traveled without needing to stop the electrophoresis prematurely.

The ability to purchase Bromophenol Blue in high purity ensures its effectiveness as a tracking dye. Its predictable behavior, coupled with its bright color, makes it easy to observe the progress of the electrophoresis even in dimly lit labs. This practical application highlights the compound's value beyond its function as a pH indicator. Researchers often look for reliable suppliers for chemicals like Bromophenol Blue to ensure consistency in their experiments. The accessibility of this chemical, often available for purchase online, makes it a convenient choice for laboratories worldwide.

When preparing samples for electrophoresis, Bromophenol Blue is typically added in a loading buffer. The concentration used is usually low, ensuring it does not interfere with the separation of the actual biomolecules. The specific bromophenol blue cas number (115-39-9) guarantees that the correct compound is being used. The visual cues provided by Bromophenol Blue are crucial for optimizing separation times, preventing samples from running off the end of the gel, and ensuring that the experiment yields meaningful data. For anyone engaged in molecular biology research, understanding the uses of Bromophenol Blue in electrophoresis is fundamental.

In summary, Bromophenol Blue is far more than just a pH indicator; it is a critical tool that brings visibility to the unseen world of molecular separation. Its role as an electrophoresis tracking dye underscores its versatility and importance in modern scientific research. NINGBO INNO PHARMCHEM CO.,LTD. is committed to supplying high-quality reagents like Bromophenol Blue to support these vital scientific endeavors.
