PS. Designed to reduce well-to-well crosstalk during fluorescent and luminescent assays.

• Square well top for easier robotic pipetting
• Round bottom for better Z factor and minimized trapped air
• Conical well molded in the shape of a light cone for efficiency
• Black walls reduce well-to-well crosstalk and autofluorescence during fluorescent assays

High binding surface is a general purpose surface that binds medium (>10kD) and large biomolecules possessing ionic groups and/or hydrophobic regions. Binding capacity is approximately 400 to 500ng IgG/cm.

Not treated (or medium binding) polystyrene surface is hydrophobic in nature and binds biomolecules through passive interactions. Suitable primarily for the immobilization of large molecules, such as antibodies, that have large hydrophobic regions that can interact with the surface (binding capacity of approximately 100 to 200ng IgG/cm²).

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.
