There are several functions of the gel matrix in electrophoresis techniques. Four of the most important are:
- The gel cut down convection currents and diffusion so that the separated components remain as sharp zones with maximum resolution between them;
- the nature of the gel (in most cases is a network of acrilamide branches or polyacrilamide) is chemically inert during the separation porcess;
- it is clearly uniform in its properties and able to be readily and reproducibly prepared; and
- the composition of the gel can be modified easily and in a controlled way varying the concengtrations of its components in order to achieve the best conditions for the problem at hand.

What gel is typically used in electrophoresis experiments?
The gel typically used in electrophoresis experiments is agarose gel.
What was used before gel electrophoresis?
Before gel electrophoresis, techniques like paper electrophoresis and agarose slab gel electrophoresis were used for separating and analyzing DNA or proteins. These methods were less efficient and had lower resolution compared to gel electrophoresis.
Can a gel electrophoresis be performed both horizonnally and vertically?
yes for example 2D gel electrophoresis
What is used to sort DNA into different lenghts?
Gel Electrophoresis
Where can one learn more on gel electrophoresis?
To learn more about gel electrophoresis, one can Google it. There is also a whole Wikipedia article dedicated to gel electrophoresis, and it happens to be quite informative.
What causes the absence of bands in gel electrophoresis?
The absence of bands in gel electrophoresis can be caused by factors such as improper loading of samples, insufficient DNA concentration, or issues with the gel or electrophoresis equipment.
What has the author A J Houtsmuller written?
A. J. Houtsmuller has written: 'Agarose-gel-electrophoresis of lipoproteins' -- subject(s): Blood protein electrophoresis, Electrophoresis, Gel electrophoresis, Lipoproteins
What do the bands in gel electrophoresis represent?
The bands in gel electrophoresis represent different sizes of DNA fragments.
In gel electrophoresis, which way does DNA move through the gel matrix?
In gel electrophoresis, DNA moves through the gel matrix from the negative electrode to the positive electrode.
Difference between vertical and horizontal gel electrophoresis?
Horizantal gel electrophoresis is generally used for RNA/DNA based studies, while vertical gel electrophoresis is used for protein based studies.
