Applications of Agarose Gel Electrophoresis

admin — Fri, 27 Aug 2021 11:44:18 +0000

Agarose gel electrophoresis is extensively used for the analysis of nucleic acid. Observations made by running DNA or RNA samples on agarose gel are very helpful to determine quantity and quality of nucleic acids. These powerful features make agarose gel electrophoresis an important essential step in many well known techniques such as northern and southern blotting, RFLP, RAPD, PCR, molecular cloning etc. Since agarose gel allows the elution of biomolecules, it can also be used for the purification of nucleic acids and large protein molecules and complexes. In addition, it can also be used to analyse biological processes such as apoptosis.

Agarose Gel Electrophoresis

admin — Thu, 19 Aug 2021 16:13:57 +0000

Agarose gel, a porous matrix, acts as a sieve through which molecules can move. The electric field is the force that forces molecules to move through an agarose gel matrix. The molecules must have a net charge, positive or negative, in order to move in an electric field. A neutral molecule will not move in an electric field.

Migration of Bromophenol Blue and Xylene Cyanol in Agarose Gel Running in TBE or TAE Electrophoresis Buffer

admin — Sun, 11 Jul 2021 12:03:08 +0000

Bromophenol blue and Xylene cyanol are the two most commonly used tracking dyes for the analysis of DNA on agarose gel electrophoresis. These negatively charged dyes not only help in monitoring the progress of agarose gel electrophoresis but also allow easy monitoring of sample loading process onto the wells of agarose gel. Their position in relation to DNA fragments is an important information that helps to determine how far a gel must be run without accidentally letting the DNA fragments of interest run out of the gel and at the same time ensuring good resolution among different size DNA fragments.

Protocol: Running DNA Samples in Agarose Gel

admin — Sun, 09 Aug 2020 21:52:43 +0000

Agarose gel is placed in an electrophoresis tank filled with an electrophoresis buffer. DNA samples are mixed with DNA loading dye and loaded onto the wells of agarose gel. Electrophoresis apparatus is connected to electric supply and electrophoresis is performed at constant voltage until the desired separation among DNA fragments is achieved. After the run is over, gel is analyzed using UV-transilluminator or Gel Doc system.

Protocol: Preparation of Agarose Gel for DNA Analysis

admin — Sun, 09 Aug 2020 21:01:23 +0000

Agarose Gel is a gelatin-like slab, which contains small wells for loading DNA samples. It is prepared by melting agarose in a suitable electrophoresis buffer. Molten agarose is then poured into a specialized tray (casting tray), which controls the size and shape of the gel. The comb is used to create wells in agarose gel.
