Tosoh TSKgel Tresyl-5PW Column, 10 μm, ID 7.5 mm x L 7.5 cm - 14456

Affinity Chromatography

TSKgel Tresyl-5PW Column, 10 μm, ID 7.5 mm x Length 7.5 cm

Unlike other TSKgel affinity columns, TSKgel Tresyl-5PW, which is derivatized with the 2,2,2-trifluroethanesulfonyl ligand, requires 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.

 Applications include: glycoproteins, antigens, etc.
