The unique saccharide-binding properties of plant lectins, such as wheat germ agglutinin (WGA), have made them useful for the study of glycosylated proteins. Lectins have been used in cell adhesion studies, to effect lymphocyte activation, and to explore carbohydrate-based therapeutics.

Bead- and column-based separation methods rely heavily on the speed and ease of affinity binding systems. Ligands such as streptavidin, antibodies and lectins are used both to capture specifically-tagged targets and for the isolation of cells and biomolecules that naturally express the ligand binding partner. The unique saccharide-binding properties of plant lectins, such as Concanavalin A (Con A) have made them useful for the labeling and isolation of glycan-presenting cells and glycoproteins in serum and cell lysate. Lectins have additionally been used in cell adhesion studies, to effect lymphocyte activation, and to explore carbohydrate-based therapeutics.

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.
