5X Sucrose Gel Loading Dye is supplied by HiMedia. This dye includes sucrose instead of glycerol. Add the dye to DNA samples prior to electrophoresis on agarose gels.

Nucleic acid loading dyes are designed to optimize loading nucleic acids in acrylamide and agarose gels. They impart colour to the sample to facilitate the loading process and increase the density of the sample to ensure efficient sample distribution into each well. The dyes migrate independently from the samples, allowing estimation of the migration of nucleic acids.
