PolyAn offers a wide range of fluorescence encoded PMMA beads and functionalized PMMA beads. Applications include multiplex bead assays, calibration of flow cytometers, calibration of fluorescence microscopes, and fluorescence lifetime-based applications. All microparticles are available in sizes between 2 – 20 µm. PolyAn also offers monodisperse, fluorescence encoded PMMA nanoparticles in the 100 – 500 nm size range. Please note, that it is possible to tailor the fluorescence intensity to your specific requirements. PolyAn also produces customized microparticles which incorporate fluorophores for other spectral ranges.
All of our fluorescent PMMA microparticles are available with 3D-Carboxy, Streptavidin or Neutravidin, 3D-Aldehyde, and Protein A/G, as well as with reactive surfaces for Click chemistry (3D-Azide, 3D-Alkyne, 3D-DBCO, and 3D-MTZ). A custom modification with other functional groups (e.g. Maleimide, Biotin,…), with different loading capacities, and the customised coupling of biomolecules (oligonucleotides, peptides, antibodies …) are also available upon request. Please do not hesitate to contact us!
With PolyAn’s production process the fluorophores are incorporated into the beads during the polymerization process. This ensures a much more homogeneous distribution of the dyes within the beads when compared to conventional diffusion controlled dyeing processes. Additionally, the fluorophores are caged within the polymeric matrix and are less likely to leak-out. Please have a look at our fluorescence encoded products.
