Gel Electrophoresis Steps: A Step-by-Step DNA Agarose Gel Protocol

Leave a Comment / Analytical, Lab Instrument, Microbiology Lab Instruments / By admin

DNA gel electrophoresis is a laboratory method used to separate DNA fragments according to their size. In agarose gel electrophoresis, DNA moves through an agarose matrix when an electric field is applied. Smaller DNA fragments generally move through the gel more easily than larger fragments, allowing researchers to separate and compare DNA samples. A well-planned …
