This Corning 96-well solid black polystyrene microplate has flat bottom wells with a 360µL total well volume and a recommended working volume of 75 to 200µL. Bottom is 60% thinner than conventional polystyrene plates, resulting in lower background fluorescence and enabling readings down to 340nm. It is designed to reduce well-to-well crosstalk during fluorescent assays. 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. It is ideal for reducing protein and nucleic acid binding at low concentrations, and increasing assay signal to noise. Conforms to standard microplate footprint and dimensions.
