3D-Carboxy functionalized microparticles

PolyAn’s 3D Carboxy microparticles with antifouling behavior are suitable for coupling of proteins, antibodies, and other amine-terminated molecules.

The activation of Carboxyl groups with EDC (1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide) and NHS (N-hydroxysuccinimide) leads to highly reactive esters, which can be easily reacted with nucleophiles, e.g. Amines or Hydrazines. The NHS-ester reacts with the NH²-groups of biochemical species to form
a covalent bond with the surface.

Key features

  • Easy activation using carbodiimide EDC
  • Generating NHS surface as an intermediate step, sequential coupling is possible
  • Amine-containing biomolecules covalently bind to activated Carboxy surface
  • Low concentration of Amine-containing biomolecules is possible
  • A stable covalent bond between the surface and the biomolecules is formed, i.e. no leaching can occur

PolyAn can functionalize all the beads from our portfolio with the Carboxy surfaces:
