Colored Latex Particles

Colored Latex Particles are uniform polymer microspheres available in a wide range of vivid, stable colors for use in diagnostics, biosensing, immunoassays, and educational or industrial applications. These colored latex beads feature monodisperse size distribution, excellent chemical stability, and high optical density, ensuring consistent performance in lateral flow assays, agglutination tests, and flow cytometry calibration. Available as plain, carboxylated, or amine-functionalized microspheres, colored latex particles can be easily conjugated with antibodies, proteins, or nucleic acids for bioconjugation, multiplex detection, and point-of-care testing. Their bright coloration, low background interference, and high visibility make them ideal for diagnostic reagents, quality control standards, and optical tracer studies.
