Bottoms are 60% thinner than conventional polystyrene plates, resulting in lower background fluorescent and enabling readings down to 340nm. 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. Ideal for reducing protein and nucleic acid binding at low concentrations, and increasing assay signal to noiseWithout lids, lids supplied separately. Recommended working volume of 75 to 200µL. Conforms to standard microplate footprint and dimensions.
