TSKgel Tresyl-5PW

TSKgel Tresyl-5PW is based on a 100 nm pore size polymethacrylate base material derivatized  with a 2,2,2-trifluroethanesulfonyl ligand. Unlike other TSKgel affinity columns, the TSKgel Tresyl-5PW columns require activation with a user-selected ligand containing amino, thiol, phenol, or imidazole groups. The resulting structure is literally a custom affinity ligand with excellent pH stability and minimal ligand loss due to leaching. TSKgel Tresyl-5PW readily reacts with amino or thiol groups to form stable covalent alkylamines or thioethers.
