TD-G50 is a gel filtration medium made of dextran as raw material and chlorinated propylene oxide as cross-linking agent. It has hydrophilic and porous characteristics and is commonly used for buffer replacement, desalination and removal of small molecules from biological samples such as proteins, polysaccharides, and nucleic acids, as well as for the separation and purification of polypeptides and oligonucleotides, and for the separation and purification of antibiotics, chemically-synthesized medicines, and natural products. It can also be used for the purification of nano-materials in chemical industry and sewage treatment in environmental protection etc.
TD-G50 separates molecules of different sizes according to the working principle of molecular sieve, based on the different retention time of molecules in the chromatographic column.
TD-G50 is divided into the following four types according to the particle size: TD-G50 C i.e. coarse particles, TD-G50 M i.e. medium particles, TD-G50 F i.e. fine particles, and TD-G50 SF i.e. super-fine particles.
