QuantumPlex™ Carboxyl 4.4 & 5.5µm

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.

QuantumPlex™ kits are available with three different surfaces to accommodate the coating strategy of choice: anti-Mouse, streptavidin, or carboxyl functional groups.
