Polystyrene Fluorescent Particles

Polystyrene Fluorescent Particles are monodisperse polymer microspheres embedded with bright, stable fluorophores for flow cytometry calibration, fluorescence microscopy, immunoassays, and bioassay applications. These fluorescent polystyrene beads provide uniform particle size, high brightness, and excellent photostability, making them ideal as fluorescence reference standards, diagnostic microspheres, and tracer particles. Available in various colors and sizes, and as plain, carboxylated, or amine-functionalized fluorescent latex beads, they allow easy conjugation with antibodies, proteins, or nucleic acids for multiplex assays, bioconjugation, and biosensing applications. Compatible with standard laser and filter systems, these fluorescent microspheres ensure reproducible intensity and reliable performance in cell analysis, flow cytometry, and nanoparticle research.
