Cross-linked dextran G-100（Cat No.:I045271）is a size-exclusion chromatography medium composed of dextran polymer chains cross-linked with epichlorohydrin to form a stable, three-dimensional gel matrix. It is designed for molecular separation based on size, with an effective fractionation range for proteins of approximately 4,000–150,000 Da. The G-100 grade provides consistent pore size, allowing reproducible separation of biomolecules in aqueous buffers. Commonly used in protein purification, desalting, and buffer exchange, cross-linked dextran G-100 offers high chemical stability, low nonspecific adsorption, and easy handling, making it valuable for biochemical, analytical, and preparative chromatography applications in research.
