Annexin-V FITC and PI staining of H-Ras 5RP7 cells to analysis apoptosis induced by silver nitrate at 6.75 µM (IC₅₀); a Control, b H-Ras 5RP7 cells were treated with an inhibition concentration of silver nitrate IC₅₀ (6.75 µM) for 24 h (Q1 necrosis, Q2 early apoptosis, Q3 viability, Q4 late apoptosis). At least 10,000 cells were analyzed per sample, and quadrant analysis was performed
