Eliminate soluble components and reduce disulfide bonds without sacrificing valuable protein or peptide samples.

• 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

The column uses a solid-phase protocol that does not require the reducing agent to be removed after the reaction. The resulting samples are free of contaminating thiols and can easily be assayed. The matrix is reusable up to four times.
