Specific aptamers obtained after multiple rounds of the SELEX process. a The binding rate of 1 μg of NGAL protein during every SELEX round, and the binding rate of NGAL protein increased from the initial 0.079% at round 1 to 1.89% at round 7. b The binding status between 53 aptamers and NGAL protein were primarily validated using the quantitative method, and ΔCt greater than 4 served as the selection standard. c The binding amounts of candidate aptamers, including NA10, NA36, NA42, NA53 and NA21 to NGAL-coated magnetic beads are much higher than those of bare magnetic beads using the qPCR method (n = 3, for each group, *p < 0.05, **p < 0.01, ***p < 0.001 vs control, and the error bars indicate the mean ± standard deviation SD)
