Seplife G25 F Dextran Size-Exclusion Medium, 1000-5000 Da (CAT#: STEM-BC-3181-ZJF)

This dextran size-exclusion medium is designed for desalting and separation of peptides and other small molecules. It consists of dextran crosslinked with epichlorohydrin to form a three-dimensional porous network. Molecules are separated according to their ability to enter the internal gel pores. Large molecules are excluded from the pores and therefore elute first. Intermediate-size molecules enter part of the pore volume and elute later. Small molecules access more of the pore network and experience the greatest retention. The fine particle range supports efficient chromatographic separation. The medium provides a stated molecular-weight separation range of 1000-5000 Da.
