What are the applications of gel electrophoresis?

Gel electrophoresis has a wide range of experimental and biomedical applications including:

• Identification and study of DNA and DNA fragments
• Study of protein and antibody interactions to gain insight into conditions such as allergies and autoimmune disorders and identify new therapies to treat those invaders
• Testing the purity and concentration of antibiotics
• Creation, production, and testing of vaccines
• Genotyping with molecular markers
