Brilliant Blue Extra Pure is a high-purity synthetic dye extensively used in laboratory research, particularly in biochemistry, molecular biology, and microbiology. It is commonly employed as a protein stain in techniques such as SDS-PAGE, where it binds to proteins for visualization and quantification. Additionally, it is used in spectrophotometric assays, as a pH indicator, and in dye tracing studies to monitor fluid movement or diffusion. The extra pure grade ensures consistent dye intensity, minimal impurities, and high solubility, making it ideal for precise analytical and experimental applications. It should be stored in a cool, dry environment, protected from light and tightly sealed to maintain its color integrity and stability.
Brilliant Blue Extra Pure
Primary Uses
Protein Staining in Gel Electrophoresis
- Widely used as a biological stain in techniques like SDS-PAGE for visualizing proteins, especially in the form of Coomassie Brilliant Blue G-250 or R-250.
pH Indicator or Tracking Dye
- Acts as a tracking dye in electrophoresis buffer systems to monitor the progress of DNA or protein migration.
Spectrophotometric Analysis
- Used in colorimetric assays for quantitative protein determination, such as the Bradford assay, due to its binding and absorption shift upon protein interaction.
Secondary Uses
Model Compound for Dye Adsorption Studies
- Employed in environmental chemistry labs to study adsorption, desorption, and filtration behavior of dyes on various media like activated carbon or clay.
Demonstrations in Analytical Chemistry
- Used in chromatography demonstrations, including paper chromatography, to illustrate migration and separation principles of polar/non-polar compounds.
Staining Agent in Microscopy
- Occasionally used for cytoplasmic or general tissue staining, especially in teaching labs to demonstrate cell structure.
