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.
