pH 3.0 (yellow) - pH 4.6 (blue) Ready-to-use reagent. Prepared with ACS reagent grade Bromophenol Blue and high purity water. Suitable for laboratory use.
Product Overview
Bromophenol Blue is a versatile dye used both as a pH indicator and as a tracking dye in electrophoresis applications. It changes color from yellow to blue over the pH range of 3.0 to 4.6, making it suitable for monitoring strong acid titrations and low-pH environments.
In molecular biology, Bromophenol Blue is widely used as a loading dye to visually track the progress of nucleic acid or protein migration during gel electrophoresis. Its low molecular weight allows it to migrate ahead of most biomolecules, giving researchers a visual cue for run completion without affecting results.
Key Features:
- pH transition range: 3.0 (yellow) to 4.6 (blue)
- Functions as both a pH indicator and electrophoresis tracking dye
- Available in powder or solution form for easy use
- Compatible with DNA/RNA and protein gel systems
- Stable and non-interfering with most analytical methods
Applications:
- Acid-base titrations in analytical chemistry
- Gel electrophoresis for nucleic acid or protein analysis
- Visual marker for sample loading and migration tracking
- Teaching tool for chemistry and molecular biology education
Bromophenol Blue is a staple in laboratories due to its dual functionality, reliability, and clear color transitions, making it an essential tool for both analytical and molecular workflows.
