How does dgge work

Although there are limitations, DGGE is an interesting and unique approach that bridges many molecular biology tools together, and its limitations are primarily attributable to the fact that it is still a relatively new technique.

It has been used frequently for identifying single-nucleotide polymorphisms without the need for DNA sequencing and as a molecular fingerprinting method for complex ecosystem communities, in particular in conjunction with amplification of microbial 16S rRNA genes.

Here, the principles of DGGE, based on partial DNA strand separation at a given position in a gradient of chemical denaturant, are described, and an example protocol, optimized for fingerprinting of — bp fragments of bacterial 16S rRNA genes, is given. Coronavirus Resources. Authors: Fiona Strathdee 1 ,. Gel casting remains the same as in example 1, although the concentration of the high and low solutions may change depending on the sequence to be analysed.

Samples will migrate to specific points in the gel depending on their sequence, and the sensitivity of this method is such that even a single base pair change can be detected. When the samples are identical, the bands present on the gel remain the same, but where mismatched occur, new bands will appear that represent a change in T m due to the formation of a heteroduplex between the two different strands. To carry out DGGE you will need some equipment that is commonly found in molecular biology laboratories, and some that is not.

To cast and run DGGE gels, you will need a gradient mixer, magnetic stirrer and optionally a peristaltic pump to pump the acrylamide solutions from the gradient mixer to the casting system.

You will also need a large vertical electrophoresis system with a heated buffer chamber. The Cleaver Scientific DGGE system is perfect for this application and can be purchased as a kit, with all the necessary equipment including gradient mixer, stirrer and peristaltic pump.

For more information on this equipment, visit the product pages below. Maximum sample throughput compatible with microplates and thermal cycler blocks. Finally, to image and document your gel, you will require a gel documentation system. For more demanding gel imaging, our complete range of gel documentation systems is available including options with touch screens, or the possibility to upgrade to chemiluminescence.
