Hi, I want to ask what is DGGE marker used for? Since there almost no commercial DGGE marker. I can make my own marker by myself, but does the marker make any sense when you analyze the DGGE gel ?
A "DGGE marker" can be helpful if you need to compare DGGE profiles of samples run on more than one DGGE gel.
As you probably know, DGGE profiles of samples are best compared if the samples are run on the same DGGE gel, since conditions between different DGGE gels are not completely identical. However, having a "marker" will allow you to align to some extent DGGE profiles obtained from different DGGE runs.
