Structure identification of AGSCS and the performance of AGSCS for detection of (1 → 3)-β-D-glucans. The structure patterns of aptamers and aptamers containing G tetramer were identified by circular dichroism. A Common aptamers, and a5-a1 represents 0.1 mol, 0.2 mol, 0.4 mol, 0.8 mol and 1 mol. B Aptamer (including G tetramer), b5-b1 represents 0.1 mol, 0.2 mol, 0.4 mol, 0.8 mol and 1 mol. C The affinity strength of original aptamers and aptamers with G-quadruplex to (1 → 3)-β-D-glucans were assayed by enzyme-linked oligonucleotide assay. NS, non-statistical significance. D We evaluated the detection ability of the AGSCS for different quantities of (1 → 3)-β-D-glucans ranging from 400 to 0.8 pg/mL. All data are shown as the means ± standard deviation, and experiments were performed in triplicates
