Color-Rich™ Dyed Particles

OptiBind polystyrene and OptiLinkcarboxylate-modified particles (medium acid content) are dyed to create the Color-Rich dyed particle product line. Color-Rich Dyed particles incorporate dyes internally. The most important characteristic for any dyed particle is visibility in the application, whether it is a visual or fluorescent microscopy technique. Internal dyeing of the polystyrene and carboxylate-modified particles insures maximum color brilliance, color saturation, prevents dye leaching in aqueous media, and leaves the surface free for optional immunological applications.Color-Rich has been specifically designed and is most often used for diagnostic lateral-flow rapid assay (membrane-based) applications.

For many types of immunological assays, the dyed particles can enhance the readability of the assay or do away with problems associated with enzyme-based assays. In addition to diagnostic assays and molecular biology applications, there are a variety of other applications where these dyed particles may be used, including membrane pore-size determinations, filtration media analysis, flow or fluid mechanism studies, particle size correlation, flow cytometry, immuno/histology studies, flow imaging tracers, cell surface antigen markers, biological transport studies and phagocytosis research.
