Polysciences' streptavidin coated beads can be used in conjunction with a biotinylated ligand, antibody, DNA or RNA to form a bridge to the microsphere, providing the simple addition of a solid support. The streptavidin-biotin bond strength approaches that of a covalent bond, with an association constant (Ka 10^15 Mol-1) in an aqueous solution. This makes the bond not only essentially irreversible, but also supplies an interaction of high affinity and specificity.

The microsphere populations in the QuantumPlex™five-bead kits are encoded with different intensities of Starfire Red™, and microspheres in our ten-bead kits are distinguished by both fluorescence intensity and size. Starfire Red™ is a fluorescent dye with unique characteristics that make it ideal for multiplexing applications. The dye's broad excitation band allows it to be excited at a number of wavelengths, and it emits in the FL3 channel (685nm) with very little carry-over into FL1 or FL2, leaving othe detectors available for determination of positive binding events via common reporters such as FITC and PE.

Fluoresbrite® carboxylate microspheres are fluorescent monodispersed polystyrene microspheres that have carboxylate groups on their surfaces which can be activated for the covalent coupling of proteins. Polysciences’ Fluoresbrite® particles are used worldwide in phagocytosis and neural retrograde transport studies, and as markers for cell bound antigens. These microspheres are packaged as 2.5% aqueous suspensions. YO has limited water solubility, and some leaching may occur with rigorous washing.
