Bio-Techne

Bio-Techne is a Minneapolis-based life science company that manufactures and sells proteins, antibodies, immunoassays, and instruments for biomedical research through its portfolio of brands including R&D Systems, Novus Biologicals, Tocris Bioscience, ProteinSimple, and Advanced Cell Technology. R&D Systems has been the gold standard supplier of recombinant cytokines, growth factors, and chemokines for over 30 years, and researchers globally rely on their proteins for stimulation and differentiation of primary cells, developing immunoassay standards, and functional studies. Their ELISA kits, particularly the DuoSet sandwich ELISA pairs, are among the most cited assay reagents in published literature. Tocris Bioscience provides a curated catalog of pharmacologically active small molecules, including receptor agonists, antagonists, enzyme inhibitors, and ion channel modulators used in neuroscience and cell biology research. ProteinSimple's Simple Western (Jess and Wes) automated western blotting instruments have transformed protein analysis by automating capillary electrophoresis-based immunodetection, dramatically reducing hands-on time and improving quantitative accuracy. Their Ella microfluidic multiplex immunoassay system enables simultaneous quantification of up to 4 proteins from small sample volumes with high throughput. Bio-Techne's Luminex multiplex bead-based assay reagents and their iStar single-plex digital ELISA platform extend their immunoassay capabilities from discovery to translational biomarker quantification.
