1. A polysaccharide extracted from seaweed, used in laboratories to form a gel matrix for separating molecules by size in gel electrophoresis.
Usage: technical; biology/biochemistry

Examples

• The DNA samples were loaded onto an agarose gel for analysis.
• Agarose is commonly used in molecular biology laboratories to separate proteins and nucleic acids.
• The researcher prepared a 1% agarose gel by dissolving the powder in buffer solution.
• Agarose gels are preferred over other matrices because they are easy to prepare and handle.
• The band pattern on the agarose gel revealed the size of the amplified DNA fragments.
