Colored Polystyrene Microspheres


Colored polystyrene microspheres are based on white polystyrene microspheres and are prepared by a unique internal dyeing process. The internal dyeing process can ensure that the color of the microspheres is full and stable. Coupling efficiency and detection sensitivity.


Perfect spherical, highly uniform particle size(CV<3%)

High chemical stability

Good monodispersity


Colored microspheres with surface-modified carboxyl groups can be coupled with antigens, antibodies, etc. by covalent bonding, and are often used in lateral immunochromatography and latex agglutination assays. We have microspheres covering a rainbow series of colors, which can meet various experimental needs in the fields of industrialization and scientific research.


Store at 2 – 8°C, do not freeze.
