UniGel Series Ion Exchange Resins, UniGel-80SP 10L (CAT#: STEM-C-3709-ZJF)

The UniGel series of ion exchange (IEX) resins includes four product types: weak cation (CM), strong cation (SP), weak anion (DEAE), and strong anion (Q). These resins are constructed from highly crosslinked polymethacrylate beads with uniform particle size and an open pore structure.
Enhanced through polyhydroxyl surface modification and tentacle surface extender chemistry, UniGel IEX resins offer exceptional binding capacity and minimal non-specific adsorption. Designed to support downstream bioprocessing, they are ideal for applications ranging from capture and intermediate purification to polishing of biomolecules, including small proteins and large biologics such as viral particles and vaccines. Their reproducibility, scalability, and reliability are well-established, making them an excellent choice for diverse purification needs.
