Agarose is a low-sulfate (salt) non-ionic polysaccharide with 1,3 linked β-D-galactose and 1,4 linked α-3,6-endoether-L-galactose alternately linked. A long-chain structure with a natural polysaccharide with high gel properties. It is widely used in the separation, analysis and identification of biological macromolecules (proteins, enzymes, nucleic acids, etc.), such as gel electrophoresis, immunoelectrophoresis, and immunodiffusion electrophoresis. Product index: Gel strength (1%) (g/cm2) ≥800 Sulfate content% ≤0.2 Electroinfiltration (-m) ≤0.15 (excellent grade), 0.20 (first grade)
