Attomole-level detection of low-abundance biomarkers using standard immunoassay workflows.
Researchers rely on immunoassays for the 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 many immunoassays.
Exazym® addresses this problem by allowing researchers to reliably detect biomarkers in extremely low concentrations. Unlike other signal amplification methods, Exazym® is an add-on reagent that can be used with existing immunoassays 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 based on a new detection method called Binding Oligo Ladder Detection, or BOLD for short. A primer conjugated to the secondary antibody works with a polymerase to create a DNA/RNA hybrid strand. This is how BOLD is able to amplify immunoassay signals by up to 100 times using established science. BOLD technology is broadly applicable for immunoassays and independent of instrument platforms. The extra amplification step can be performed between 20°C to 37°C. This temperature range makes BOLD ideally suited for temperature-sensitive ligands and antibodies.
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.
