label: Description (Brief)
content: Electrophoresis combs are used to create the wells in gels for electrophoresis, a technique that uses the electrical charges of molecules to separate them by their length. It is often used to analyze DNA fragments. When a gel is poured, a comb is inserted. After the gel solidifies, the comb is removed, leaving wells for samples.
