Introducing Exazym®
immunoassay signal amplification

Both researchers and clinical decision-makers rely on immunoassays for the precise detection of biomarkers. When test samples contain abundant concentrations of analyte the process is relatively straightforward. However, the ability to detect biomarkers in low concentrations and distinguish them from background noise has been a limiting factor for all immunoassays.

Exazym® (patent pending) addresses this problem by allowing researchers and clinicians to reliably detect biomarkers in extremely low concentrations. Unlike other signal amplification methods, Exazym® is an add-on reagent that can be used with any existing immunoassay to dramatically lower the limit of detection without the need for expensive equipment or proprietary processes.

The BOLD science behind Exazym®

Binding Oligo Ladder Detection (BOLD)

Exazym® is an add-on reagent licensed to immunoassay kit producers. It is based on a new detection method called Binding Oligo Ladder Detection, or BOLD for short. A primer conjugated to the detection antibody works with polymerase to create a long ladder of DNA to which secondary antibodies with reporter molecules selectively bind. This is how BOLD is able to amplify immunoassay signals by up to 100 times using established science. For optimal amplification the reaction should take place at a constant temperature of 37°C, although it’s possible to achieve excellent results at room temperature.

Amplifies signal 10-100 times - Low background - Works with any immunoassay

Transforming translational research

Translational research serves as the vital link between scientific breakthroughs and real-world clinical diagnostics, treatments, and cures. Any significant advance in this field is a win for humanity.

That is why we are so excited about the promise that Exazym holds for translational research globally. Once adopted by kit producers, our BOLD (Binding Oligo Ladder Detection) technology will put cutting-edge immunoassay sensitivity within every researcher’s grasp.
