Develop high-quality, highly sensitive Point of Care diagnostic assays with Thermo Scientific Color-Rich™ dyed beads. Our internal dyeing methods provide exceptional color saturation, prevent dye leaching in aqueous media, leave the surface free for covalent coupling, and enable maximum immunological reactivity. Available visible dyes include Green, Red and Blue for the Color-Rich Dyed Carboxylate-modified beads and Red and Black for the ChromoSphere Dry Dyed beads for specialized applications.
Key Applications
Obtain superior test sensitivity in qualitative and quantitative lateral flow tests with Thermo Scientific™ Color-Rich Dyed Carboxylate-Modified Particles. Higher intensity dyed particles provide maximum color and brilliance, as well as immunologically reactive surfaces. These particles are composed of polystyrene with or without a copolymer grated surface for fast coupling and processing reactions. Available in blue, red or black internally dyed versions, these hydrophilic particles can bind ligands without any dye interference, feature high protein binding capacity; and have an optimized acid content.
Achieve high visual contrast with Thermo Scientific™ ChromoSphere™ Dry Dyed Particles, polymer particles that are internally and deeply dyed in intense red or black, resulting in very high contrast and visibility relative to most background materials. Available as dry powders that can be easily suspended in aqueous media, the product line consists of a large assortment of uniform, red or black particle sizes between 50μm and 500μm.
