Description

Acid Blue 83 is also known as Coomassie Brilliant Blue, a synthetic dye made from triphenylmethane. The name “Coomassie Brilliant Blue”, which comes from the discoverer of the dye and the initial commercial company that produced it, is a synthetic triphenylmethane dye. Coomassie bright blue, from a chemical perspective, is a highly-conjugated organic molecule, with a triphenylmethane structure composed of three aromatic ring connected by a carbon atom in the middle, and a sulfonic group attached to it. This sulfonic group is what allows Coomassie Brilliant Blue to be water-soluble and form sodium or potassium salts. It is therefore classified as “acidic”. Coomassie Brilliant blue can both dissolve in water and bind positively charged fibers via ionic bonding in acidic dye baths. In commercial products, Coomassie brilliant blue is usually a fine powder in brownish purple or deep purple red. This ensures rapid dissolution and uniform color. Coomassie Brilliant Blue’s most notable physical properties are its unique color expression and excellent solubility. It is easily soluble in water and forms a bright, clear blue-purple solution. Coomassie Brilliant Blue is also soluble in polar organic solvants such as ethanol and methanol. However, it has poor solubility with non-polar solvants. The solution of Coomassie Brilliant Blue has a high color strength. This means that it is able to produce rich and clear colors even at very low concentrations. This is due to its high molar absorbtivity which allows it to absorb light. Coomassie Brilliant Blue also exhibits an important and well-known physicochemical property: its binding to proteins. When it binds with the hydrophobic area of the protein, the maximum absorption peak undergoes redshifting, and the absorbance of that wavelength is markedly increased. It is because of this property that it has become a widely used biochemical reagent. The Coomassie Brilliant Blue exhibits excellent chemical stability both in the solid and solution state, but it may slowly degrade over time under extreme pH conditions.

The application of Coomassie brilliant blue

Coomassie Brilliant Blue is used for a variety of purposes.

Acid Blue 83 is also known as Coomassie Brilliant Blue. It’s a “dual-star” product that can be used in industrial dyeing or life science research.

1. Key reagents for biochemistry and molecular biological research

The most popular and irreplaceable use of Coomassie Brilliant Blue in modern laboratories is based on the specific binding it has to protein molecules.

Coomassie Brilliant Blue is used in the classic application. The researchers stained the gel using the dye solution containing Coomassie Brilliant Blue as the main component after SDS polyacrylamide electrophoresis.

According to this principle, dye molecules are bound specifically to the hydrophobic regions of proteins by van der Waals interactions and hydrophobic forces. After binding, the dye-protein complex absorbance in the visible light area is greatly enhanced. The colorless bands of protein in the gel now appear blue.

This method is called “Coomassie Brilliant Blue Staining Method”. Coomassie Brilliant Blue has a lower sensitivity than silver staining but it is more convenient, faster, cheaper, offers a wider linear range and is compatible with most proteins. It is now a standard for routine protein quantification and detection in laboratories.

Bradford protein quantification was developed based on the binding principle above. Coomassie Brilliant Blue G250, which is the most commonly used dye in this method, can be used to determine protein concentrations based on similar principle. A linear relationship exists between the change in absorbance due to the dye binding to the proteins and the protein concentration in a given range. This allows for the determination of the concentration of proteins using a spectrophotometer.

Staining agents, tracers and tracer:

Coomassie Brilliant Blue can be used to enhance the contrast in biological microscopy. It can also be combined with other dyes for a more intense contrast.

It is added to the buffer in agarose gel electrophoresis as a leading marker to monitor the migration of DNA fragments. This is because the small molecules of dye run ahead of the DNA fragments.

2. Textile and Fiber Dyeing

Coomassie Brilliant Blue can be used in the same way as an acidic color, but primarily for positively charged fibers.

It can also give silk fabrics vibrant and bright blue-purple tones while maintaining their unique luster.

Coomassie brilliant can be used to dye wool yarns, fabrics and finished products. It provides a deep blue color with good fastness.

3.Color paper and leather

Coomassie brilliant can be used for a variety of colored papers such as art paper, gift wrap paper, decorative paper and more. The paper can have a unique look thanks to its brightly colored light.

Coomassie brilliant can be used to dye leather, as it can penetrate the leather’s interior and produce an uniform translucent appearance. It can be used to dye clothing leather in blue or purple, as well as furniture leather and luggage leather.
