96 Well Half-Area Thin-Bottom NBS Microplates, Black

Treated or non-treated surface models Black or clear versions Can be used for both top and bottom reading instruments 96 Half-Area Well microplates are available in a range of configurations. Bottoms are 60% thinner than conventional polystyrene plates resulting in lower background fluorescence and enabling readings down to 340 nm. Some models feature nonbinding NBS™ surface, a Corning proprietary treatment technology used on polystyrene microplates to create a non-ionic hydrophilic surface (polyethylene oxide-like) that minimizes molecular interactions making it suitable for reducing protein and nucleic acid binding at low concentrations, and increasing assay signal to noise. Other models offer TC-treated surfaces. Their opaque walls to prevent well-to-well crosstalk and optically clear flat well bottoms permit direct microscopic viewing. Microplates are sterilized by gamma radiation and certified non-pyrogenic. Models that are not treated feature a polystyrene surface that is hydrophobic in nature and binds biomolecules through passive interactions. They are suitable primarily for the immobilization of large molecules, such as antibodies, that have large hydrophobic regions that can interact with the surface. Untreated microplates have a binding capacity of approximately 100 to 200 ng IgG/cm 2 .
