Fig. 5From: Combination of Quercetin or/and siRNA-loaded DDAB-mPEG-PCL hybrid nanoparticles reverse resistance to Regorafenib in colon cancer cellsThe X-axis shows the various concentrations of the diluted drugs (in mg/dL) and the Y-axis shows the degree of absorption reported as Optical density (OD) A Calibration curve in Quercetin (n = 3) with 95% CI. B Calibration curve Regorafenib (n = 3) with 95% CIBack to article page
