Color-Rich™ Carboxylated-modifed particles

Color-Rich™ Dyed Carboxylate-modified Particles provide maximum color and brilliance, as well as immunologically reactive surfaces. Composed of polystyrene or polystyrene with a copolymer grated surface for fast coupling and processing reactions, these hydrophilic particles enable users to optimize lateral flow assays by controlling sensitivity, specificity and stability; are available in blue, red or black internally dyed versions; can bind ligands without any dye interference; feature high protein binding capacity; and have an optimized acid content.Lateral Flow Test Development

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 1) covalent coupling through a COOH group, and 2) optimal immunological reactivity. Bind ligands without dye interference
Dye-free surface for coupling
High protein binding capacity
Hydrophilic—readily adsorbs and couples proteins
Optimizes assays by controlling sensitivity, specificity and stability
Optimized acid content
Easy one-step covalent coupling protocols
Ensures reproducibility
The 0.4µm nominal diameter (DB1040CA through DBK1040CB) is the optimal size for most latex-based lateral flow tests
The coefficient of variation (CV) of the diameter is less than 5%, ensuring uniform migration through membranes.
