International ClassA61M 001/10AbstractThis invention pertains to a method for immobilizing polyethylene oxide (PEO) star molecules in the form of hydrogels. the PEO star molecules are biocompatible and demonstrate non-thrombogenic properties. As such, the PEO star molecules have numerous uses for biomedical applications. The hydrogels contain a high percentage of terminal hydroxyl groups for attachment of affinity ligands and can be used for separating and purifying therapeutic proteins.Other References
