StabilBlock? Immunoassay Stabilizer effectively preserves the conformation and activity of dried proteins while simultaneously blocking the surface to reduce non-specific binding. It can be used to stabilize antibodies, antigens or enzymes on an assortment of immunoassay components including polystyrene plates, tubes, glass, membranes, and filter paper. The key benefits are reduction of non-specific binding while increasing signal-to-noise ratios within immunoassay applications.
