SDS-PAGE Loading Dye 4X is a high-quality concentrated buffer designed for preparing protein samples for SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis). This dye ensures accurate and efficient protein separation by providing essential components for sample denaturation and visualization.

The formulation contains SDS, glycerol, bromophenol blue, and stabilizers. SDS acts as a detergent to denature proteins and impart a uniform negative charge, enabling their separation based on molecular weight. Glycerol helps samples sink smoothly into gel wells, while bromophenol blue serves as a tracking dye during electrophoresis.

With its 4X concentrated formulation, the SDS-PAGE Loading Dye can be easily diluted to the desired working concentration, making it ideal for a wide range of protein analysis and electrophoresis applications in molecular biology and biochemistry research.
