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.

Introduction: Electrophoresis is a powerful technique used in various scientific fields, including DNA analysis. In this case study, we will explore the application of electrophoresis in forensic DNA profiling, specifically in a criminal investigation.

Background: A crime scene investigation has been initiated for a burglary case. The investigators found biological evidence at the crime scene, including bloodstains on a broken window. The DNA from the bloodstains needs to be analyzed to identify the perpetrator.

Objective: The objective is to extract DNA from the bloodstains and analyze it using gel electrophoresis to determine the DNA profile. The DNA profile will then be compared with the DNA of potential suspects to identify the burglar.

Methods:

  1. Sample Collection and DNA Extraction:
    • Bloodstain samples are collected from the crime scene using sterile swabs.
    • DNA extraction is performed using a suitable extraction method, such as phenol-chloroform extraction or a commercial DNA extraction kit.
  2. PCR Amplification:
    • Polymerase Chain Reaction (PCR) is used to selectively amplify specific DNA regions of interest.
    • Short Tandem Repeat (STR) markers commonly used in forensic DNA analysis, such as the FBI CODIS markers, are amplified.
  3. Preparation of DNA Samples for Electrophoresis:
    • The PCR-amplified DNA samples are mixed with a loading dye containing tracking dyes for visualization.
    • 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.
  5. Visualization and Analysis:
    • The gel is stained with a DNA-binding dye, such as ethidium bromide or SYBR® Green.
    • The DNA bands are visualized using UV transillumination or a gel imaging system.
    • The resulting DNA profile is analyzed, and the sizes of the amplified STR fragments are determined.
