General description

  • Black wall plates have reduced autofluorescence, higher signal to background ratio and lower CV′s.
  • 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

Note: Suggested replacement for CLS3654
Non-Binding surface (NBS) multiwell plates have a modified polymer surface (PS) which results in a non-ionic hydrophilic surface (polyethylene oxide-like), thereby minimizing bio-interaction and enhancing the signal-to-noise ratio. Results have demonstrated NBS′s ability to significantly reduce protein and nucleic acid binding to polymers (<2 ng/cm2; over 90% reduction of protein binding compare to PS & PP surface), maintain enzyme activity, and inhibit adhesion of a number of cell lines. These novel surface technologies for assay plates are ideal for homogeneous assays such as Scintillation Proximity Assay (SPA). In addition to a 20+ fold increase in signal-to-noise ratio, selected assays have also displayed improved sensitivity and specificity. The recommended working volume of up to 20 μL to 80 μL for 384 well plates.
