Description
For Covalent Protein Attachment
Our activated polyethersulfone (PES) membrane offers rapid covalent protein immobilization via an aldehyde chemistry. The membrane possesses stable aldehyde functional groups on its inner and outer
surfaces, which provide for effective covalent binding to amine groups on
proteins. Proteins can be efficiently attached to this surface without prior chemical derivatization over wide pH ranges. The membrane can immobilize immunoglobulin to a density of 135 µg/cm 2.
The aldehyde functionality is stable and inert to moisture and heat, eliminating the need for special storage.The membrane is available in two formats, supported and unsupported, to accommodate your manufacturing needs.
