Gel electrophoresis is a laboratory technique used to separate and analyze macromolecules such as DNA, RNA, and proteins based on their size and charge. The basic process involves the following key components and steps: 1. **Gel Matrix**: A gel, commonly made from agarose or polyacrylamide, serves as a medium through which the molecules will travel. The pore size of the gel can be adjusted by varying its concentration, allowing for separation of different sizes of molecules.
Technique widely used to measure the size of DNA strands, most often PCR output of a region of interest.
A simple sample application is gel electrophoresis alelle determination.
