Agarose gel electrophoresis.
The gel typically used in electrophoresis experiments is agarose gel.
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.
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.
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.

The bands in gel electrophoresis represent different sizes of DNA fragments.
In gel electrophoresis, DNA moves through the gel matrix from the negative electrode to the positive electrode.
Horizantal gel electrophoresis is generally used for RNA/DNA based studies, while vertical gel electrophoresis is used for protein based studies.
If the pH value becomes lower than the protein's isoelectric point (pI) in 2D gel electrophoresis, the protein will acquire a net positive charge due to the excess of protons. This will cause the protein to move towards the cathode during electrophoresis.
