Nonbinding (NBS™) surface is a Corning proprietary treatment technology used on polystyrene microplates to create a nonionic hydrophilic surface (polyethylene oxide-like) that minimizes molecular interactions. Ideal for reducing protein and nucleic acid binding at low concentrations, and increasing assay signal to noise. Without lids, lids supplied separately. Recommended working volume of up to 75 to 200µL. Conforms to standard microplate footprint and dimensions.
