Spot Capture and
Detection System

For immunoprecipitation, protein purification & immunofluorescence

ChromoTek’s proprietary and novel Spot-System is the first peptide-tag specific Nanobody for universal capture & detection applications. It comprises the Spot-Tag®, an inert 12 amino acid peptide-tag (PDRVRAVSHWSS), and Spot-Nanobodies that specifically bind to Spot-tagged proteins with high affinity.

Applications & Tools:

  • Immunoprecipitation (IP) / Co-IP: Spot-Trap®
  • Co-IP/MS: Spot-Trap and iST Spot-Trap Kit
  • Protein purification: Spot-Cap®
  • Immunofluorescence: Spot-Label®
  • Western Blotting: Spot-tag antibody [28a5]
