Gel Electrophoresis Explained: The Foundation of Molecular Analysis Techniques - starpoint
Gel electrophoresis is a laboratory technique that separates DNA, RNA, or proteins based on their size and charge. It involves placing a sample onto a gel matrix, typically made of agarose or polyacrylamide, and applying an electric field. The charged molecules migrate through the gel at different rates, depending on their size and charge, resulting in a separated and resolved pattern.
A: While gel electrophoresis does require careful sample preparation and handling, the actual process is relatively straightforward.
