These negatively charged dyes not only help in monitoring the progress of agarose gel electrophoresis but also allow easy monitoring of sample loading process onto the wells of agarose gel. Their position in relation to DNA fragments is an important information that helps to determine how far a gel must be run without accidentally letting the DNA fragments of interest run out of the gel and at the same time ensuring good resolution among different size DNA fragments.
