TD-G25 series media is a gel filtration media made of dextran as raw material and epichlorohydrin as cross-linking agent, with hydrophilic and porous characteristics, commonly used in biological samples such as proteins, polysaccharides and nucleic acids, etc. buffer replacement, desalination and removal of small molecules, but also can be used for the separation and purification of polypeptides and oligonucleotides, as well as the separation and purification of antibiotics, chemically synthetically synthesized drugs and natural products, but also can be used for the purification of nanomaterials in the chemical industry and the environmental protection field, such as wastewater treatment.
TD-G25 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.
The TK-Col G25F series desalting pre-packed columns are ready-to-use columns featuring TD-G25F (fine-particle) media packed into TK-EC empty columns. This eliminates the hassle of self-packing chromatography columns and is commonly used for buffer exchange, desalting, and removal of small molecules from biological samples such as proteins, polysaccharides, and nucleic acids. The perfect integration of media and chromatography columns makes chromatography efficient and straightforward.
