Reactive Blue 4 is an anthraquinone-based reactive dye characterized by its intense blue color and strong affinity for proteins and other biomolecules. Its color stability and binding properties make it a valuable reagent for biological research, textile processing, analytical studies, and environmental applications. It is commonly used in laboratory research to stain proteins on electrophoretic gels. It has been used for labeling antibodies. It can also interact with proteins, making it a useful immobilized ligand in protein separation systems. It is also employed in textile dyeing because it forms strong bonds with fibers, producing durable color. It is also studied in environmental research as a model dye for studying dye degradation and wastewater treatment methods.
