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.
GelRedâ¢ and GelGreenâ¢ are highly sensitive either as precast gel stains or post gel stains. GelRedâ¢ is much more sensitive than EtBr, and at least as sensitive as or brighter than SYBRÂ® Gold in post gel staining. Unlike SYBRÂ® Gold, GelRedâ¢ can also be used as a highly sensitive precast gel stain. GelGreenâ¢ is spectrally similar to SYBRÂ® Safe but is far more sensitive, and can be used with blue light gel imaging systems like the DarkReaderÂ®. PAGE GelRed and PAGE GelGreen are designed for staining DNA in acrylamide gels.
