Bioptix

World-class research doesn't make compromises, so BiOptix exists to make superior label-free detection technologies more accessible to researchers worldwide. BiOptix has developed a new class of analytical biosensor instrumentation utilizing a patented high-throughput label-free technology known as ESPR – Enhanced Surface Plasmon Resonance - which was developed by BiOptix in conjunction with Dr. John ‘Jan’ Hall, Professor Adjunct of Physics at the University of Colorado, who was awarded the Nobel Prize for Physics in 2005. Our flagship ESPR product is the 404pi, a groundbreaking SPR instrument providing scientists that require label-free, real-time detection of biomolecular interactions with an extremely high sensitivity, low noise instrument at a price point that is hundreds of thousands of dollars less than systems with equivalent performance. The 404pi concurrently offers industry-leading reliability, easy to use software for experimental design and instrument control, greater experimental flexibility, and far lower operating costs than competing instruments. BiOptix instrumentation allows researchers to study almost any biomolecular interaction in a label-free manner, including protein-protein interaction, protein-small molecule interaction, antibody-antigen interactions, and much more. Further applications include include kinetic rate determination, fragment screening, epitope mapping and affinity measurement. For more information, please visit our website at
