Using an electric field, molecules (such as DNA) can be made to move through a gel made of agarose or polyacrylamide. The electric field consists of a negative charge at one end which pushes the molecules through the gel, and a positive charge at the other end that pulls the molecules through the gel.

DNA fragments smaller than 100 bp are more effectively separated using polyacrylamide gel electrophoresis. Unlike agarose gels, the polyacrylamide gel matrix is formed through a free radical driven chemical reaction. These thinner gels are of higher concentration, are run vertically and have better resolution.

The QIAEX II and QIAquick Gel Extraction Kit can be used to extract DNA from polyacrylamide gels.. The QIAEX II Handbook contains a protocol for Polyacrylamide Gel Extraction. A specialized User-Developed Protocol (QQ05) is available when using the QIAquick Gel Extraction Kit for this purpose.. Both protocols require the preparation of a diffusion buffer and a disposable plastic column or ...

Polyacrylamide Gel Electrophoresis has a number of advantages, which are: PAGE has a high loading capacity, up to 10 micrograms of DNA can be loaded into a single well (1 cm x 1 mm) without significant loss of resolution. Polyacrylamide contains few inhibitors of enzymatic reactions.

DNA fragments resolved on polyacrylamide gels can also be visualized by the method of UV shadowing. In this method the gel is placed on top of a fluorescent material, usually a flourescent TLC silica plate. The gel is then illuminated by a UV light source. DNA bands in the gel will block transmittance of the UV light to the substrate.

The basics. Agarose gels can be used to resolve large fragments of DNA. Polyacrylamide gels are used to separate shorter nucleic acids, generally in the range of 1−1000 base pairs, based on the concentration used (Figure 1). These gels can be run with or without a denaturant. Gels that are run without a denaturant are referred to as native gels.

This ensures that any slight difference in the concentration of salts between the gel and the running buffer is run into the gel before the DNA is loaded and thus won't cause irregular migration ...
