Used extensively in biochemistry for staining proteins in gel electrophoresis, enabling visualization and quantification of protein bands. It binds to proteins through electrostatic and hydrophobic interactions, providing a blue color that can be analyzed using imaging systems. Commonly employed in Bradford protein assays to measure protein concentration in samples due to its sensitivity and ease of use. Also utilized in histology for staining tissue sections to study protein distribution. Its application is critical in research, diagnostics, and quality control in pharmaceutical and biotechnological industries.
