Applied Microspheres expertise lies in the production of (polymer) nano- and microspheres with very narrow size distributions. These can be produced in large batches, for long term supply and stability. Surface chemistries can be modified for conjugation the of antibodies, proteins and other biomolecules and a wide variety of dyes can be "hard dyed" into the polymer matrix. Particle size, surface chemistry and dye profiles can be customised to meet specific requirements. Applied Microspheres also supplies glass microspheres and magnetic beads. Applications: Diagnostic assay development (lateral flow, agglutination, flow cytometry multiplex, particle enhanced turbidimetry), instrument controls, purification.
