Electrophoresis is a technique used to separate charged molecules in an electric field based on their mobilities, while isotachophoresis is a specific type of electrophoresis that separates analytes based on differences in their electrophoretic mobilities. Isotachophoresis uses a leading electrolyte and a terminating electrolyte to create zones of analytes, resulting in highly efficient separations.

What is a common name for gel electrophoresis?
Agarose gel electrophoresis.
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
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.
When is DNA cut during electrophoresis?
Electrophoresis technique is not designed to cut DNA molecule. When DNA is analyzed by electrophoresis to determine its molecular mass, the molecular biology engineer usualy digests the DNA molecule, before the electrophoresis, with specific enzymes called "restriction enzymes" in order to obtain fragments of diverse molecular weights that can be seen as bands in electrophoresis gels.
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.
Difference between TBE and TAE buffers?
TBE (Tris-borate-EDTA) buffer is used for nucleic acid electrophoresis and provides better resolution of larger DNA fragments, while TAE (Tris-acetate-EDTA) buffer is commonly used for agarose gel electrophoresis of DNA. The primary difference between the two buffers is the anion used (borate vs. acetate), which can affect the mobility of DNA fragments during electrophoresis.
Similarities between gel electrophoresis and paper chromatography?
nothing

When was Electrophoresis - journal - created?
Electrophoresis - journal - was created in 1980.
What is a common name for gel electrophoresis?
Agarose gel electrophoresis.

Why is gel electrophoresis important?
To separate and analyze DNA fragments and protein fragments by weight. If you have digested some bacterial DNA, for instance, then you can tell by running the fragmented DNA in the gel whether you have digested the correct base length.
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.
How is DNA separated into distinct bars (what is the difference between the bars at the bottom vs the bars at the top)?
Nucleic acid electrophoresis is an analytical technique use to separate DNA or RNA. The DNA fragments of different lengths are visualized using a fluorescent dye
What is the difference between agar and agarose?
Agar is a gelatinous substance derived from seaweed, commonly used in microbiology for culturing bacteria. Agarose is a type of agar that has been purified and is specifically used in gel electrophoresis for separating DNA fragments based on size.
What is the role of EtBr in electrophoresis?
Ethidium bromide interchalates with DNA. It doesn't affect electrophoresis, but it help visualise the DNA bands after electrophoresis. The EtBr that is bound to the DNA will fluoresce under ultraviolet light.
