TentaGel & Hypogel Resins

TentaGel & Hypogel Resins

TentaGel® resins consist of low cross-linked polystyrene on which poly(ethylene glycol) with a molecular weight of 3000 Da is grafted. The PEG spacer is attached to the polymer matrix via an ether bond, which shows high stability towards acid treatment and minimizes PEG leaching. TentaGel® resins are pressure stable and can be used in batch processes as well as under continuous flow. If high swelling is desired, TentaGel® XV (XV = extended volume) shows superior result. If shorter PEG chains are preferred, HypoGel 200 (five PEG units, 200 Da) and HypoGel 400 (ten PEG units, 400 Da) have been developed.
