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.
PolyAn offers a wide range of fluorescence encoded PMMA beads and functionalized PMMA beads. Applications include multiplex bead assays, calibration of flow cytometers and calibration of fluorescence microscopes. All microparticles are available in sizes between 2 – 20 µm. Please note, that it is possible to tailor the fluorescence intensity to your specific requirements. PolyAn also produces customised microparticles which incorporate fluorophores for other spectral ranges.
All of our fluorescent PMMA microparticles are available with 3D-Carboxy, Streptavidin, Protein A and 3D-Alkyne surface chemistry. A custom modification with other functional groups (e.g. Protein G, Neutravidin, …) with different loading capacities and the customised coupling of biomolecules (oligonucleotides, peptides, antibodies …) are also available upon request.
