Covalent binding surfaces for Immunoassays

PolyAn´s reactive microplates are beneficial for immobilizing biomolecules that inefficiently coat by passive adsorption. PolyAn offers amine-binding and nucleophilic binding surfaces as well as 3D-Azide plates for bio-orthogonal binding via click-chemistry.

Key features

  • Reactive surfaces for covalent immobilization ensure minimal leaching
  • Withstands rigorous washing
  • Minimal unspecific binding due to 3D functional matrix
  • Control of orientation of the probe to be immobilized and even directed (bio-orthogonal) immobilization possible

Description PolyAn's 3D-NHS functionalized 96-well microplates are used for covalent immobilization of biomolecules. The NHS-ester reacts immediately with the NH2- terminus of biochemical species to form a covalent bond with the surface.

The plates are offered for colorimetric, chemiluminescence and fluorescent detection systems, respectively. Please go to this section for glass bottom plates with a wide range of surfaces and well designs. Additionally, PolyAn offers functionalized, solvent stable microplates that are comprised of Polypropylene (PP) as well as covalently coated Streptavidin and Neutravidin plates.
