Seplife G100 SF Dextran Size-Exclusion Medium, 4000-100000 Da (CAT#: STEM-BC-3190-ZJF)

This superfine dextran size-exclusion medium is designed for protein purification, molecular-weight measurement, equilibrium-constant determination, and cell separation. It uses epichlorohydrin-crosslinked dextran with a three-dimensional porous structure. Molecules are separated according to their hydrodynamic size. Large components are excluded from the pores and elute first. Intermediate components enter part of the pore network and elute later. Smaller components access a larger internal volume and experience greater retention. The 10-40 µm particles support high-resolution analytical and preparative separations. The stated fractionation range is 4000-100000 Da.
