Abstract
Isothermal exponential amplification technology has rarely been fabricated as a universal sensing platform for the detection of proteins. To broaden their application, we have developed a strategy, named protein-recognition-initiated exponential amplification reaction (PRIEAR) using protein recognition to induce DNA assembly, which converts protein recognition events into ssDNA amplicons and combines two-stage amplification to achieve exponential amplification. Taking advantage of this principle, diverse biomarkers can be quantified at sub-picomolar concentrations in a homogenous manner, making PRIEAR suitable for clinical settings. Therefore, this strategy can expand the powerful isothermal exponential amplification technology to protein targets and thus provide a new toolbox in clinical and biomedical applications.
