Capillary electrophoresis is a technique used in laboratories to separate molecules based on their charge in order to study and analyze them. Capillary electrophoresis uses an electric charge to force the movement of molecules since each molecule will go a varying distance based on the weight of the molecule and their charge. Some areas of study that use capillary electrophoresis include DNA sequencing and pharmaceutical analysis.

What is Capillary Electrophoresis?
Capillary electrophoresis (CE), also known as capillary zone electrophoresis (CZE), can be used to separate ionic species by their charge and frictional forces. In traditional electrophoresis, electrically charged analytes move in a conductive liquid medium under the influence of an electric field. Introduced in the 1960s, the technique of capillary electrophoresis (CE) was designed to separate species based on their size to charge ratio in the interior of a small capillary filled with an electrolyte. While its use has been sporadic, CE offers unparalleled resolution and selectivity allowing for separation of analytes with very little physical difference. Efficiencies of millions of plates are routinely reported. Once thought impossible, separation of large proteins differing in only one amino acid (ie. D-Lysine substituted for L-Lysine) and even an isotopic separation of 14N and 15N ammonium hydroxide have been reported.[1] No other technique has shown such powerful selectivity with the ability for extremely high sensitivity. As few as 6 molecules of a substance have been separated and detected with the help of laser-induced fluorescence (LIF).
One lane of an electrophoresis gel shows a 100bp ladder. What is the purpose of this ladder?
It is used as a marker for molecular weight.
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.
How do you know which molecule is the smallest in a DNA fingerprint?
The smallest molecule travels fastest once the current is switched on.If the process is slab gel electrophoresis, the smallest molecule (or rather, about 200 million of them following PCR or some other process of amplification) will be the one nearest the positively-charged end of the gel.If the analysis is by capillary electrophoresis, the smallest molecule will be the first one to pass the window and interrupt the laser beam.
What are the application of paper electrophoresis?
Paper electrophoresis is used to analyze scientific experiments. One use in scientific experiments for paper electrophoresis is to determine the presence of HIV from blood samples.
What is the conclusion on the application of gel electrophoresis?
One of the Conclusion of electrophoresis is Visualization of the DNA size. Second is Sequencing the length of DNA of the body.
What is capillary action due to?
The adhesive intermolecular forces between the substance rising (the one experiencing capillary action) and the container (typically a capillary).
What is the structure of a capillary?
they are one cell thick.
What is a sentence for capillary?
1.There are many capillaries in your body. 2.You do not only have one capillary in u`r body but many.
Why the capillary has only one Epithelial cell?
It has only one flow of blood.
Is a capillary a vessel?
where the blood travels from the lungs to left the atria.^^^ This answer is wrong in every salient way. Use the Wikipedia entry here: http://en.wikipedia.org/wiki/Capillary
Is there any liquid that does not exhibit capillary action?
There are many. For just one example, mercury has a concave meniscus in a capillary, i.e., it tries to go down, not up.
