Electrophoresis

Electrophoresis is a laboratory technique used to separate and analyze molecules based on their size and charge. It involves applying an electric field to a gel or liquid medium containing the molecules of interest. The molecules, such as proteins or nucleic acids, move through the medium under the influence of the electric field.

In gel electrophoresis, the medium is typically a gel matrix made of agarose or polyacrylamide. The gel provides a sieving effect, allowing smaller molecules to migrate faster than larger ones. By adjusting the conditions, such as the strength of the electric field or the composition of the gel, different types of molecules can be separated.

There are various types of electrophoresis techniques, including:

1. SDS-PAGE (Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis): Used for separating proteins based on their molecular weight.
2. Agarose Gel Electrophoresis: Used for separating DNA or RNA fragments based on their size.
3. Native-PAGE: Used to separate proteins under native conditions without denaturing them.
4. Capillary Electrophoresis: Analyzes molecules in a narrow capillary tube, enabling high-resolution separations.

Electrophoresis has applications in various fields, including molecular biology, biochemistry, genetics, forensics, and clinical diagnostics. It is a powerful tool for studying biomolecules, identifying genetic variations, and analyzing protein composition.

The AIIMS chemistry syllabus for the advanced course does not specifically mention electrophoresis. However, electrophoresis is a technique widely used in biochemistry and molecular biology. It is used to separate and analyze macromolecules such as proteins, nucleic acids, and carbohydrates based on their size and charge.

If you are specifically interested in studying electrophoresis, you may find it covered under broader topics such as biochemistry, molecular biology, or analytical chemistry. It is advisable to refer to textbooks and course materials that cover these areas in more detail.

   • The samples are denatured and heated to disrupt DNA secondary structures.
4. Gel Electrophoresis:
   • Agarose gel electrophoresis is performed to separate the amplified DNA fragments based on size.
   • A DNA ladder of known fragment sizes is loaded as a size reference.
   • Electrophoresis is carried out in a buffer solution under an electric field for a specified period.
