Protein and DNA electrophoresis are two types of gel electrophoresis methods with a few significant differences. 

Protein electrophoresis:

• Is a technique used to separate proteins based on size and charge
• The procedure uses a polyacrylamide gel, which has smaller pores
• Is more time-intensive and requires specialized equipment and reagents

DNA electrophoresis:

• Is a technique used to separate DNA based on size and charge
• The procedure uses an agarose gel
• Is less time-intensive and does not require specialized equipment or reagents
