琼脂糖（用于凝胶电泳）

Agarose (for gel electrophoresis) is a polysaccharide extracted from seaweed, widely used in molecular biology. It serves as an essential component in the preparation of gels for DNA and RNA separation. Key applications include nucleic acid electrophoresis, blotting, and immunodiffusion. This product is particularly valued in the pharma and biotech industries for its high gel strength, low electroendoosmosis, and excellent thermal stability.
