This illustration depicts a gel electrophoresis setup with a gel electrophoresis tank filled with buffer solution. The tank includes a gel with blue bands, likely representing separated DNA, RNA, or protein fragments. The setup has black and red electrodes for applying an electric field to facilitate the movement of molecules through the gel matrix. The illustrated electrophoresis tank is green, while the electrodes are black and red. The entire setup is essential for molecular biology, biochemistry, life sciences, bioinformatics, and biotechnology laboratories for the analysis of nucleic acids and proteins.
