Gel Loading Dye, Blue (6X) is a Bromophenol Blue-based loading dye offering convenient gel loading and sharp bands. bromophenol blue front At the end of the run the power pack was switched off The from CHEMISTRY 3101 at GC University Lahore Bromophenol blue has a slight negative charge and will migrate the same direction as DNA, allowing the user to monitor the progress of molecules moving through the gel. The composition of agarose gel controls the moving position of bromophenol blue in the gel. Loading Dye Buffers contain glycerol that ensures that the DNA in the ladder and sample forms a layer at the bottom of the well, and color markers (e.g. The rate of migration varies with gel composition. Product use limitations As Dominique's said, uses of the two dyes are to track the DNA molecule in the gel during the course of gel electrophoresis. The 6X Loading Dye buffer is used to prepare DNA ladders and samples for loading on agarose or polyacrylamide gels.
