Agarose gel electrophoresis is a method used in biochemistry and molecular biology to separate DNA, or RNA molecules by size. This is achieved by moving negatively charged nucleic acid molecules through an agarose matrix with...

Agarose gel electrophoresis. A matrix composed of a highly purified form of agar that is used to separate larger DNA and RNA molecules ranging 20,000 nucleotides. (See Electrophoresis.) ...
Agarose gel prepared for DNA analysis - The first lane contains a DNA ladder for sizing, and the other four lanes show variously-sized DNA fragments that are present in some but not all of the samples.
Agarose gel electrophoresis
Following DNA digestion, the resulting DNA fragments are separated by size via electrophoresis in agarose gels. During electrophoresis, DNAs which are negatively charged migrate toward the positive electrode.
AGAROSE GEL ELECTROPHORESIS - A method for separating nucleic acids (DNA or RNA) within a gel made of agarose in a suitable buffer under the influence of an electrical field.
Agarose gels: A polysaccharide gel used to measure the size of nucleic acids (in bases or base pairs). See "Gel Electrophoresis".
Northern analysis -- a technique for transferring electrophoretically resolved RNA segments from an agarose gel to a nitrocellulose filter paper sheet via capillary action.
A method for detecting specific DNA fragments seperated on an agarose gel. DNA fragments are first seperated by electrophoresis through an agarose gel. After electrophoresis, the DNA in the gel is denatured by soaking the gel in an alkaline solution.

a technique for transferring DNA fragments separated by agarose gel electrophoresis to a nitrocellulose filter on which specific DNA fragments can be detected using specific radioactive DNA probes; devised by E. Southern ...
These fragments can be visualized by subjecting the digestion mixtures to electrophoresis in an agarose gel. Because of its negatively-charged phosphate groups, DNA migrates toward the positive electrode (anode) when a direct current is applied.
Southern Blot A technique named after Prof. Ed Southern in which, after electrophoresis in agarose gels, DNA is transferred to a membrane where it can be analysed by hybridisation with a probe. See blot ...
The PCR product is then digested with a restriction enzyme and the products separated on an agarose gel.
This is because, mutations apart, the phage sequence will always be the same, and so EcoR1 cutting sites will always be present in the same places. The fragments can be separated and their sizes determined by agarose gel electrophoresis.
