XanTec bioanalytics GmbH Information

XanTec bioanalytics GmbH develops the surface chemistry that makes label-free biosensing work. We are a team of specialists in surface chemistry, organic synthesis, biology and physics, dedicated to one thing: engineering the bio-interface between your sample and the sensor. Our portfolio covers four core product groups: SPR sensor chips — including CMD, HC, NiHC His-tag capture, streptavidin, protein A/G, click chemistry and custom matrices — compatible with Biacore, Reichert, Bruker Sierra, Carterra LSA, Sartorius, BioNavis and other major SPR platforms. SPR instruments — benchtop and research-grade SPR systems for kinetic characterisation, affinity measurement and fragment screening, supplied alongside matched chip chemistries for fully integrated workflows. Microarray slides — functionalised glass slides for protein, antibody, peptide, DNA and glycan microarrays, with surface chemistries tuned for low background, high spot homogeneity and reproducible printing. Nanometer biocoatings — functional surface modifications for plastic, glass and metal substrates, used in microfluidics, diagnostic assays and OEM device manufacturing. From standard catalogue products to fully custom surface chemistries, we support biomolecular interaction analysis, kinetic characterisation, protein profiling and assay development worldwide — from method development through to OEM-scale production. Based in Düsseldorf, Germany, used in labs across 40+ countries.
