How to fill out 2d gel electrophoresis

How to fill out 2D gel electrophoresis:

Prepare the gel and running buffer:

1. Cast a polyacrylamide gel with the desired concentration and thickness.
2. Prepare the running buffer, such as Tris-glycine or Tricine-SDS buffer, at the appropriate pH and concentration.

Sample preparation:

1. Extract and isolate proteins from the biological sample of interest.
2. Determine the protein concentration using a suitable method, such as the Bradford assay.
3. Mix the protein sample with an appropriate loading buffer, usually containing a reducing agent and a tracking dye.

Loading the gel:

1. Load the protein sample onto the gel using a micropipette or a specialized sample applicator.
2. Be careful to not overload the gel and ensure even distribution of the sample.

Electrophoresis:

1. Carefully place the gel into the electrophoresis apparatus, ensuring proper alignment between the anode and cathode chambers.
2. Fill the chambers with the running buffer, ensuring complete submersion of the gel.
3. Apply a constant voltage or current and run the gel at the appropriate conditions based on the protein size range and desired separation resolution.
4. Monitor the progress of the gel electrophoresis by observing the migration of the tracking dye.

Staining and visualization:

1. After electrophoresis, carefully remove the gel from the apparatus.
2. Stain the gel using a suitable protein stain, such as Coomassie Brilliant Blue or silver stain, following the manufacturer's instructions.
3. Destain the gel to remove excess dye and enhance the visibility of protein bands.
4. Visualize the protein bands using appropriate imaging techniques like UV transilluminator, scanner, or specialized gel documentation system.
