Seplife G100 M Dextran Size-Exclusion Medium, 4000-100000 Da (CAT#: STEM-BC-3191-ZJF)

This dextran size-exclusion medium is designed for protein purification, molecular-weight determination, equilibrium-constant studies, and cell separation. It consists of dextran crosslinked through ether bonds to form a porous gel network. Molecular components are separated according to their ability to enter the internal pores. Large molecules are excluded and move through the column more rapidly. Intermediate molecules enter some of the pore volume and elute later. Smaller molecules access more of the matrix and experience greater retention. The 40-120 µm particles support general preparative operation. The stated fractionation range is 4000-100000 Da.
