Agarose consumables for gel electrophoresis are essential components used in the preparation of agarose gels, which are widely employed for the separation and analysis of nucleic acids, such as DNA and RNA. Agarose is a polysaccharide derived from seaweed that forms a gel-like matrix when dissolved in buffer and cooled, allowing for the effective resolution of nucleic acids based on size during electrophoresis. These consumables come in various grades and concentrations to suit different experimental needs, offering optimal resolution for fragment sizes ranging from a few base pairs to several kilobases. Agarose consumables also include gel casting trays, combs, and buffers, which collectively facilitate the preparation and running of gels. The reliable performance of agarose gels is crucial for applications in molecular biology, genetics, and forensic science, enabling researchers to visualise and analyse genetic material accurately.
