Round well design with a solid white flat bottom. 2.8 mm distance between well bottoms to plate bottom. Ideal for miniaturized 384 well fluorescent homogeneous assays. Nonbinding surface (NBS™) 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
