In this project, you will construct a basic electrophoresis apparatus to separate dyes based on their charge and molecular size. This experiment demonstrates the principles of electrophoresis, a technique used in laboratories for separating molecules.
If dyes are separated using electrophoresis, then they will travel different distances based on their charge and size.

Prepare the agarose gel by dissolving the agarose powder in the electrophoresis buffer and heating it.
Pour the molten agarose into the gel casting tray and insert the comb to create wells.
Once the gel solidifies, place it in the electrophoresis tank and cover it with buffer.
Load dye samples into the wells using a micropipette.
Connect the electrophoresis tank to the power supply and run the current for a designated time.
Turn off the power and carefully remove the gel.
Stain the gel using the staining solution to visualize the separated dyes.
Observe and document the distances traveled by each dye under UV light.
Analyze the results and compare the migration patterns of different dyes.
Clean up the workspace and dispose of chemicals safely.
Dyes in the mixture will separate into distinct bands on the gel. The distance traveled by each dye will vary based on its charge and molecular size.

Wear safety goggles and gloves when handling chemicals. Ensure proper ventilation when using staining solutions.
Create a detailed diagram of your electrophoresis setup.
Include photos of the gels before and after staining.
Explain the principle of electrophoresis in simple terms.
Discuss real-world applications of electrophoresis.
Dyes travel different distances based on their charge and size, affecting how they move through the gel matrix.
The buffer solution maintains a stable pH and conducts electricity during the electrophoresis process.
Yes, electrophoresis can be used to separate proteins using specific gels and conditions.
