The Covalent Advantage
Covalent binding creates a stable chemical bond between biomolecules and a surface, helping prevent wash-off, displacement and loss of function. This Knowledge Paper explains how Culturon’s plasma-activated coatings enable reagent-free covalent immobilisation of proteins and other biomolecules, and why this can improve reproducibility, sensitivity and experimental performance.
Why covalent binding matters
Conventional laboratory plastics typically rely on passive adsorption, which can result in weak or inconsistent biomolecule attachment.
Culturon’s plasma-activated coatings create reactive surfaces that enable covalent biomolecule immobilisation without additional linker chemistry.
Covalent attachment can reduce biomolecule wash-off and displacement during experimental workflows.
More stable surface attachment can improve reproducibility, sensitivity and consistency across assays and cell culture applications.
Culturon’s surface technology can be applied across a range of life science applications where control of the biological interface matters.
The Covalent Advantage Knowledge Paper explores the surface science behind this approach and its implications for researchers seeking more reliable and controllable biological surfaces.
