Immune evasion and biocompatibility of AR-NADR in vitro. A Fluorescence images of RAW264.7 cells after culture with NADR, R-NADR, and AR-NADR for 6 h. B Mean fluorescence intensity of RAW264.7 cells after various treatments for 6 h. C The cell viability of HUVECs treated with NADR, R-NADR, and AR-NADR for 24 h. D Quantification of hemolysis of RBCs at various concentrations of NADR, R-NADR, and AR-NADR at 37 °C for 2 h. Data are presented as the means ± SD (n = 3) (intergroup comparisons: ****p < 0.0001)
