Electrophoresis is a technique used for the separation of biological molecules based on their movement due to the influence of a direct electric current. The technique was pioneered in 1937 by the Swedish chemist Arne Tiselius for the separation of proteins. It has now been extended to the separation of many other different classes of biomolecules including nucleic acids, carbohydrates and amino acids. Electrophoresis has become increasingly important in the laboratory for basic research, biomedical research and in clinical settings for the diagnosis of disease. Electrophoresis is not commonly used to purify proteins in large quantities because other methods exist which are simpler, faster, and more efficient. However, it is valuable as an analytical technique for detecting and quantifying minute traces of many biomolecules in a mixture. It is also useful for determining certain physical properties such as molecular mass, isoelectric point, and biological activity.
Electrophoresis is commonly used in laboratories to separate and analyze molecules based on their size, charge, and shape. It is widely used in molecular Biology and biochemistry for DNA sequencing, protein analysis, and studying genetic variations. Electrophoresis is also used in forensic science for DNA profiling and in medical diagnostics for identifying diseases.
Gel electrophoresis is used extensively in forensic sciences. The most useful application is comparing two DNA samples to determine if they're matches. If two samples of DNA are the same, then when they are cut by the same restriction enzymes, the fragment bands should be in the same position/distance for both gels.
The motion of charged particles in a colloid under the influence of an electric field; particles with a positive charge go to the cathode
Electrophoresis is a motion, not a thing. These are used in DNA, affinity, capillaries, electrofocusing, and pulsed field gel settings.
Electrolysis of Water:
Water (H2O) --> Hydrogen (H2) + Oxygen (O)
It can be used to prove a suspect guilty /innocent of a crime. It can also be used to confirm the father of a baby.
Gel Electrophoresis is comonly used in paternity testing. It compares the father or mother's DNA to the childs DNA.

What process uses electricity to seprate organic compounds?
The process that uses electricity to separate organic compounds is called electrophoresis. Electrophoresis involves applying an electric field to a solution containing the compounds, causing them to migrate at different speeds based on their charge and size, allowing for their separation.
Some viva voce questions for electrophoresis?
1. WHAT IS ELECTROPHORESIS AND WHAT ARE THE IMPORTANTAPPLICATIONS OF ELECTROPHORESIS?Ans. Movement of charged particle in the electric field either towards cathode or anode whensubjected to an electric current is called electrophoresis.The following factors influence the movement of particles during the electrophoresis.(a) Electric current.(b) Net charge of the particle.(c) Size and shape of the particle.(d) Type of supporting media.(e) Buffer solution.Important Applications of ElectrophoresisThe technique of electrophoresis is used to separate and identify the(i) Serum proteins(ii) Serum lipoproteins(iii) Blood hemoglobins2. WHAT ARE THE DIFFERENT TYPES OF ELECTROPHORESIS?Ans. (a) Moving boundary electrophoresis: This technique was first introduced by TISELIUS in 1937(b) Zone electrophoresis: In this type of electrophoresis different types of supporting mediaare used. These are;(a) Paper electrophoresis(i) Whatman filter paper(ii) Cellulose acetate(b) Gel electrophoresis(i) Agarose.(ii) Polyacrylamide gel (used for the separation of isoenzymes).(iii) SDS-PAGE.(iv) Iso-electric focussing (proteins seperated in a medium possessing a stable pH gradient).(v) Immuno electrophoresis (for the separation of immunoglobulins).
What process uses electricity to seperate organic compounds?
Electrolysis is a process that uses electricity to separate organic compounds by passing an electric current through a solution containing the compounds. This results in the compounds being broken down into their individual components based on their electrochemical properties.
What color tube is drawn for a hgb electrophoresis?
A lavender-top (EDTA) tube is typically used for drawing blood samples for hemoglobin electrophoresis testing.
What color test tube for protein electrophoresis?
For protein electrophoresis, a clear or colorless test tube is typically used. This allows for easy visualization of the protein bands after electrophoresis is complete. Any other colored test tube could interfere with accurate observation and analysis of the results.
What process uses electricity to seprate organic compounds?
The process that uses electricity to separate organic compounds is called electrophoresis. Electrophoresis involves applying an electric field to a solution containing the compounds, causing them to migrate at different speeds based on their charge and size, allowing for their separation.
What are the scientific uses for polyacrylamide?
it is used in gel electrophoresis.....for the separation of DNA fragments
What process uses electricity to separate organic compound?
electrophoresis
For what purpose might one use capillary electrophoresis?
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 the difference between electrophoresis and isotachophoresis?
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.

When was Electrophoresis - journal - created?
Electrophoresis - journal - was created in 1980.
What is a common name for gel electrophoresis?
Agarose gel electrophoresis.
What has the author B J Haywood written?
B. J. Haywood has written: 'Electrophoresis - technical applications' -- subject(s): Abstracts, Bibliography, Electrophoresis 'Electrophoresis-technical application' -- subject(s): Bibliography, Electrophoresis
DNA fragments can be separated and analyzed by?
gel electrophoresis, a technique that uses an electric field to separate DNA fragments based on size. The smaller DNA fragments move faster through the gel, while larger fragments move more slowly. This allows researchers to determine the sizes of DNA fragments in a sample.
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
