Agarose Gel Electrophoresis of Nucleic Acids

After amplify DNA template using PCR method, now you can continue your work by using gel electrophoresis in a gel composed of agarose in order to separate DNA fragments based on its molecular weight. The percentage of agarose used depends on the size of fragments to be resolved. In general a 0.8-1% gel may be used for effective separation of DNA fragments of 100-1500 base pairs.
