Surface functionalized Microparticles
PolyAn’s high-performance polymer microparticles are functionalized with a 3D surface chemistry comprised of a long-chain polymer with a defined number of reactive groups. In contrast to conventional coating procedures, the reactive polymer is covalently linked to the surface.
By using MSE-technology, a thin polymer shell of a few nanometers, consisting of carboxyl groups, is formed on the surface. This occurs without changing the excellent physical and optical properties of the PMMA-core. Our 3D-Carboxy microparticles are suitable for EDC/EDAC mediated coupling of amine-containing molecules or for ionic interaction.
PolyAn offers the following surfaces for immobilization of DNA, peptides and proteins:
- 3D-Carboxy for EDC/EDAC mediated coupling
- 3D-Alkyne for "click chemistry"
- 3D-Streptavidin for coupling of biotinylated biomolecules
- 3D-Neutravidin for coupling of biotinylated biomolecules
- Protein A for binding of IgG
- Protein G for binding of IgG
Unspecific binding and aggregation of biomolecules is reduced by our antifouling functionality. Our rigorous quality control procedures according to ISO 9001 ensure the constant loading and low batch-to-batch variation necessary for molecular diagnostics and pharma screening.
