Color-Rich Dyed Carboxylate-Modified Particles

Thermo Scientific* 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 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.

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

Recommended for: Clinical diagnostics, molecular biology and lateral flow, turbidimetric, and slide aggulation assays
