DNA Agarose Gel Electrophoresis02:35

DNA Agarose Gel Electrophoresis

Agarose gel electrophoresis is a laboratory technique commonly used to separate DNA fragments by size. However, it can also be used to isolate and purify DNA fragments using a gel extraction protocol.
Gel extraction follows five major steps: running gel electrophoresis to separate fragments, isolating the individual bands, extracting DNA from those bands, and removing the dye and salts from the extracted mixture to obtain pure DNA.
In cloning experiments, both the insert and vector DNA...
Two-dimensional Gel Electrophoresis01:22

Two-dimensional Gel Electrophoresis

Two-dimensional gel electrophoresis is a high-resolution protein separation method first introduced by O' Farrell and Klose in 1975. This method involves protein separation by two dimensions, mass and charge, making it more accurate than one-dimensional gel electrophoresis.
The first dimension separation uses the isoelectric focusing or IEF technique performed on immobilized pH gradient (IPG) strips that separate proteins according to their isoelectric points.
Biological samples, such as  cells...
Southern Blot02:57

Southern Blot

Agarose gel electrophoresis is very useful in separating DNA fragments by size. Running a DNA ladder containing fragments of the known length alongside the sample helps determine the approximate length of the sample DNA fragments. However, additional steps are needed to verify the sequence identity of the sample DNA fragments.
Denatured DNA fragments must be transferred onto a carrier membrane from the gel to make it accessible to a probe - a small ssDNA fragment complementary to the target DNA...
Electrophoresis: Overview01:20

Electrophoresis: Overview

Electrophoresis is a powerful analytical separation technique that relies on the differential migration of charged species when subjected to an electric field. The core strength of electrophoresis lies in its ability to separate high-molecular-weight species in complex mixtures. It has found widespread use in biochemistry, molecular biology, and analytical chemistry, allowing the separation of compounds like amino acids, nucleotides, carbohydrates, and proteins with excellent resolution.

Area of Science:

  • Neuroscience
  • Molecular Biology
  • Genetics

Background:

  • Neurons adapt to brain injury via induced transcription factors.
  • These factors alter gene expression in response to neurotoxins, neurodegeneration, or mechanical damage.

Purpose of the Study:

  • To elucidate the role of transcription factors in neuronal adaptation and fate determination following brain injury.

Main Methods:

  • Analysis of transcription factor induction in injured neuronal models.
  • Investigation of DNA-binding protein interactions with gene promoter regions.
  • Correlation of specific transcription factor expression with regenerative or degenerative gene regulation.

Main Results:

  • Transcription factors are key mediators of neuronal response to diverse brain injuries.
  • These proteins bind specific DNA sequences to control gene transcription.
  • The balance of expressed transcription factors dictates neuronal survival or demise.

Conclusions:

  • Transcription factor expression is a critical determinant of neuronal fate after injury.
  • Targeting specific transcription factors may offer therapeutic strategies for brain injury and neurodegenerative diseases.
