ProMTag reversible protein tag


SKU: T-6000 Category:

ProMTag protein tagging agent reacts with the surface of proteins or peptides at pH 8.0 to tag a protein sample in just 30 minutes.  The ProMTag-proteins may then be captured on ProMTag capture resin (sold separately) for protein enrichment, concentration, desalting, or for buffer exchange.  The ProMTag is removed from the protein surface and proteins released from the ProMTag capture resin in 15 minutes by incubating in an acidic buffer of your choice. Rapidly tag, capture, and release your protein(s) for any number of applications.  Use with our ProMTag Capture Tubes and waste collection set for faster washes and elution and less protein loss. This tagging agent should be paired with our ProMTag Capture Resin for best results.  If you need help designing or customizing your workflow to meet your needs, contact us at and we would be happy to assist you.
