Acrylamide Gel Electrophoresis. Polyacrylamide gel electrophoresis provides very high resolution of DNA molecules 10–3,000 bp long. Under the appropriate conditions, DNA molecules differing in size by only a single base pair can be resolved (learn more: Nucleic acid electrophoresis education ). We offer convenient reagents for polyacrylamide gel electrophoresis, including hassle-free precast Invitrogen Novex polyacrylamide gels, DNA ladders, and UltraPure reagents for pouring your own gels.
Cross-linked chains of polyacrylamide, introduced as matrices for electrophoresis by Raymond and Weintraub (1959), are used as electrically neutral gels to separate double-stranded DNA fragments
