Purple Latex Particles

Purple Latex Particles are monodisperse polymer microspheres infused with bright, stable purple fluorophores for flow cytometry calibration, fluorescence microscopy, immunoassays, and bioassay applications. These purple fluorescent latex beads provide uniform particle size, high brightness, and excellent photostability, making them ideal for fluorescence reference standards, diagnostic assays, and nanoparticle tracking.Available as plain, carboxylated, or amine-functionalized latex microspheres, they can be easily conjugated with antibodies, proteins, or nucleic acids for bioconjugation, multiplex assays, and cell labeling studies. Optimized for Cy5, far-red, and compatible excitation lasers, these purple latex particles deliver reproducible fluorescence intensity, long-term stability, and low background signal, ensuring accurate results in molecular diagnostics, biosensing, and fluorescence-based research.
