Color-Rich Dyed and Fluoro-Max Fluorescent Particles (for lateral flow tests)

Higher intensity dyed particles provide superior test sensitivity in qualitative and quantitative lateral flow tests.

These particles are internally dyed using the Thermo Scientific Color-Rich internal dyeing method or by utilizing the proprietary Firefli fluorescent dyeing process. Color-Rich dyeing methods provide exceptional color

saturation, prevent dye leaching in aqueous media, and leave the surface free for covalent coupling and optimal immunological reactivity.

Color-Rich Dyed and Fluoro-Max fluorescent particles have been specifically designed for diagnostic lateral-flow rapid assay (membranebased) applications. However, these particles can also be used in other applications such

as clinical diagnostics, immuno/histological studies and molecular biology.

The 0.4 μm nominal diameter is the optimal size for most membrane-based lateral flow tests. The coefficient of variation (CV) of the diameter is less than 5%, ensuring uniform migration through membranes.
