Bestdex G-25 series resin is made by dextran as raw material. Featuring hydrophilicity and multiple pore sizes, the product is widely used for buffer exchange、desalting and small molecule removal of bio-organism samples(protein, polysaccharide and nucleic acid). It can also be used for separation of peptide, oligonucleotides as well as the purification of antibiotics, chemical synthesized medication and natural organism. Besides, application to nanotechnology and sewage disposal is becoming increasingly commonplace.
Functioning as molecular sieves, Bestdes G-25 series separate molecules in various sizes according to the variety in retention time of molecules in the column. Bestdex G-25 is divided into four types based on particle size: Bestdex G-25 C (coarse), Bestdex G-25 M (Medium), Bestdex G-25 F(Fine), and Bestdex G-25 SF (Super fine).
