Seplife G50 M Dextran Size-Exclusion Medium, 50-150 µm (CAT#: STEM-BC-3186-ZJF)

This dextran size-exclusion medium is designed for desalting, peptide separation, biological-extract cleanup, and molecular-weight measurement. It uses an epichlorohydrin-crosslinked dextran matrix with a porous three-dimensional network. Molecular separation is governed by access to the internal pore volume. Large molecules are excluded from the gel and elute before smaller components. Intermediate molecules enter some pores and show moderate retention. Small molecules penetrate more of the matrix and elute later. The medium particle range supports general preparative chromatography. The stated fractionation range is 1500-30000 Da.
