What is slab gel electrophoresis?

Slab gel electrophoresis has become a ubiquitous tool in the bioscience laboratory for the analysis of polynucleotides in such applications as sequencing, restriction mapping, PCR and mutational analysis. The most common media for slab gel electrophoresis are polyacrylamide and agarose [ 73 ].

Which media is used for slab gel electrophoresis?

The most common media for slab gel electrophoresis are polyacrylamide and agarose [ 73 ]. Polyacrylamide is typically used for smaller molecules while agarose is used for larger molecules because of its larger pore size. For many separations involving polynucleotides, polyacrylamide gel electrophoresis (PAGE) is the standard methodology.

Why is polyacrylamide gel electrophoresis important?

III. CONCLUSION The use of polyacrylamide gel electrophoresis to analyze and to separate complex mixtures of proteins and nucleic acids has greatly enhanced our understanding of many cellular and viral systems.

Why is polyacrylamide gel electrophoresis used in gliadin separation?

The gel used in this process is thinner, allowing for a more efficient separation process. The separation of wheat proteins, in particular gliadin, is achieved with high resolution which can be achieved by polyacrylamide gel electrophoresis [ 31, 32 ].

What is slab-gel electrophoresis used for?

Slab-gel electrophoresis has often been employed for the separation of biomacromolecules such as proteins and nucleic acids. In order to separate proteins according to size, they have to be denaturated using saturation with SDS. The separation is obtained by electrophoresis of the proteins through a suitable polymer that acts as a molecular sieve.

What techniques are used in slab gel electrophoresis?

Some typical techniques using slab gel electrophoresis include Southern blotting whereby analytes are transferred from the slab gel to an immobilizing membrane allowing them to be more easily accessible.
