The Loading Dye * Loading dye is a colored buffer mixed with the DNA prior to loading onto the gel. The loading dye contains a relatively high concentration of either glycerol or sucrose. This makes the solution more dense than the surrounding running buffer so that when a sample is pipetted over top of a well it sinks down into the well.
Possible reason for the selective adsorption of cationic dyes is due to the electrostatic attraction between the adsorbents and cationic dyes. Compared with UiO-66, UiO-66-NH 2 shows higher adsorption capacity for cationic dyes and lower adsorption capacity for anionic dyes.iO-66 and UiO-66-NH 2 with small size and large surface area were successfully synthetized by a facile solvothermal method, and both of them can remove cationic dyes from solution more effectively than for anionic dyes.
