Differbetween
Gel electrophoresis can be conducted in either a horizontal or vertical orientation. ... Thus, DNA and RNA molecules are more often run on agarose gels (horizontally), while proteins are run on acrylamide gels (vertically).

What is the difference between horizontal and vertical blotting?
One of the key differences between the two systems is their orientation. In horizontal gel electrophoresis, the gel matrix is cast horizontally and submerged in a continuous running buffer while in vertical gel electrophoresis, the gel is vertically oriented and the buffer system is discontinuous.
Why agarose gel electrophoresis is horizontal?
Horizontal Gel Electrophoresis
Due to DNA and RNA are negatively charged, they migrate from a negative end to a positive end. The agarose gel contains small pores which allow the migration of small molecules. Hence, once the electric field is applied, DNA and RNA start to migrate.
Why is Protein Electrophoresis done vertically?
The vertical system allows you to make them sequentially. You add the resolving gel first and then once it is set, you add the stacking gel. It would be very difficult, if not impossible, to make a gel like this in a horizontal system. The second reason is that oxygen inhibits the polymerization of SDS-PAGE gels.
What are the two types of electrophoresis?

What are the types of electrophoresis?
Types of Electrophoresis:
- Capillary electrophoresis. Gel electrophoresis. Paper electrophoresis.
- Slab electrophoresis. Zone electrophoresis. Immunoelectrophoresis. Isoelectrofocusing.
Why buffer is used in electrophoresis?
Buffers in gel electrophoresis are used to provide ions that carry a current and to maintain the pH at a relatively constant value. These buffers have plenty of ions in them, which is necessary for the passage of electricity through them.
What is the difference between SDS PAGE and gel electrophoresis?
The main difference between gel electrophoresis and SDS PAGE is that gel electrophoresis is a technique used to separate DNA, RNA, and proteins whereas SDS PAGE is a type of gel electrophoresis used mainly to separate proteins. Generally, SDS PAGE gives a better resolution than the regular gel electrophoresis.
What is the principle of electrophoresis?
Principles. Electrophoresis is a general term that describes the migration and separation of charged particles (ions) under the influence of an electric field. An electrophoretic system consists of two electrodes of opposite charge (anode, cathode), connected by a conducting medium called an electrolyte.
What is the principle of agarose gel electrophoresis?
Principle: The negatively charged DNA molecules migrate towards the positive charge under the influence of constant current, thus the separation depends on the mass and charge of DNA. The DNA molecules are forced to move through the agarose gel pores.
What is the purpose of SDS-PAGE?
SDS-PAGE is an analytical technique to separate proteins based on their molecular weight. When proteins are separated by electrophoresis through a gel matrix, smaller proteins migrate faster due to less resistance from the gel matrix.
What are the applications of gel electrophoresis?
Applications of gel electrophoresis
- In the separation of DNA fragments for DNA fingerprinting to investigate crime scenes.
- To analyze results of polymerase chain reaction.
- To analyze genes associated with a particular illness.
- In DNA profiling for taxonomy studies to distinguish different species.
How is gel electrophoresis carried out?
Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.
