Colorimetric Detection of Class A Soybean Saponins by G-Quadruplex-Based Hybridization Chain Reaction

<div>Colorimetric detection of the <i>GmSg-1</i><sup><i>a</i></sup> and <i>GmSg-1</i><sup><i>b</i></sup> using the HCR assays. (a) The photograph illustrates the colorimetric results of tubes 1–6 by adding different hairpin probes and target genes. Tube 1: GAa1 + GAa2 + TAa. Tube 2: GAa1 + GAa2 + TAb. Tube 3: blank. Tube 4: GAb1 + GAb2 + TAa. Tube 5: GAb1 + GAb2 + TAb. Tube 6: blank. (b) The corresponding results of 3% agarose gel electrophoresis.</div>
