Seakem Le Agarose (Routine Mol Bio Purpose) is supplied by Lonza. SeaKem LE Agarose is an all-purpose agarose for routine nucleic acid electrophoresis of fragments between 500bp-23,000 bp. SeaKem LE Agarose has no detectable DNase or RNase activity. Agarose is a polysaccharide, generally extracted from certain red seaweed. It is a linear polymer made up of the repeating unit of agarobiose, which is a disaccharide made up of D-galactose and 3,6-anhydro-L-galactopyranose. Agarose is one of the two principal components of agar, and is purified from agar by removing agar's other component, agaropectin.

Agarose is frequently used in molecular biology for the separation of large molecules, especially DNA, by electrophoresis. Slabs of agarose gels (usually 0.7 - 2%) for electrophoresis are readily prepared by pouring the warm, liquid solution into a mold. A wide range of different agaroses of varying molecular weights and properties are commercially available for this purpose. Agarose may also be formed into beads and used in a number of chromatographic methods for protein purification. Agarose is a preferred matrix for work with proteins and nucleic acids as it has a broad range of physical, chemical and thermal stability, and its lower degree of chemical complexity also makes it less likely to interact with biomolecules. Agarose is most commonly used as the medium for analytical scale electrophoretic separation in agarose gel electrophoresis. Agarose is also used widely for a number of other applications, for example immunodiffusion and immunoelectrophoresis, as the agarose fibers functions as an anchor for immunocomplexes.
