Surface matters

Find valuable information about products relating to passive binding surfaces for biomacromolecules, covalent coupling surfaces for smaller biomolecules, and affinity capture surface for affinity-tagged biomolecules. Our diagnostic solutions have more than 30 years of industry-leading experience in immunoassay plate technology.

Featured diagnostic assay development plates categories

Blank microplates (96-well) for passive adsorption (coating) antibodies, proteins, and other biomolecules for ELISA and other assay techniques.

Streptavidin, antibody, nickel, and other ligand-coated microplates (96-well) for affinity binding of proteins and other biomolecules for ELISA and other assay techniques.

Functionally-activated microplates for covalent attachment of peptides, nucleic acids, and other biomolecules for ELISA and other plate-based assay techniques. These plates bind with funcitonal groups such as amino (NH2), sulfhydryl (SH), carboxyl (COOH), and phosphate (PO4).  

Covalent crosslinking and affinity-binding microplates (96-well) for immobilizing nucleic acids (oligos, oligonucleotides, etc.) for plate-based assay techniques.

Solid Phase Guide

What is the best type of surface for my needs?

Whatever the format chosen, there are a number of choices to be made about the best type of surface for the application. The choice will depend on the assay component to be immobilized. Our Solid Phase Guide is an introduction to solid phase techniques, including:

  • Solid phase formats and surfaces
  • Parameters affection coating
  • Assay conditions for ELISA
  • Immobilization of DNA
