Pierce™ Immobilised reductant column contains beaded resin to which an thiol-based reducing agent has been immobilised to enable solid-phase reduction of peptide and protein disulphide bonds.

• Eliminates soluble components which interfere with the assay of free thiol groups
• No need to remove reducing agent after the reaction
• Reduced protein, free of contaminating thiols, can be easily assayed using the BCA method
• Solid phase; protocols for both peptides and proteins
• Excellent protein recovery
• Regenerable matrix useable up to four times
