3D-Aldehyde functionalized beads for direct coupling of biomolecules

Aldehyde groups react immediately with the NH2-terminus or other suitable functional groups of the probe to form a (covalent) bond with the surface. Thus, no activation of the bead surface is necessary prior to binding of the probe. The 3D-Aldehyde matrix has an integrated spacer structure to ensure optimal binding conditions. If necessary, the loading with Aldehyde groups can be adapted to the specific application.

  • Aldehyde groups bind to Amines, Hydrazines and Aminoalkoxyacetyl modified biomolecules
  • Suitable for one-step coupling of biomolecules, no activation of surface with Glutaraldehyde necessary
  • Different Aldehyde loadings on beads are possible
  • Wide range of sizes to choose from - 2 μm to 20 μm
  • Both transparent and fluorescence encoded beads as well as multiplex beads are available

PolyAn can functionalize all the beads from our portfolio with the new 3D-Aldehyde surfaces:

As part of our functionalization services PolyAn is now also offering the custom modification of beads with probes. Please do not hesitate to contact us (mail@poly-an.de), if you have any questions regarding our products. We are looking forward to your inquiry.
