Glycerol Gel Loading Dye, 5X (contains 30% Glycerol), is designed for DNA sample loading in electrophoresis. This 1mL vial is a concentrated solution that provides both color and density to DNA samples, ensuring easy visualization and proper migration during electrophoresis. The glycerol ensures that samples sink into the wells of the agarose gel, facilitating better sample tracking and accurate results. The dye also provides color for visual confirmation of the sample's position in the loading well, improving ease of analysis. Laboratories use this dye routinely for DNA sequencing, PCR analysis, and other electrophoresis applications, especially in molecular biology and genetic research.
