Fig. 5From: Comparative cytotoxic activity of Convolvulus pluricaulis against human hepatoma cell line (HepG2) and normal cell line (L929) via apoptosis pathways by flow cytometry analysisFlow-cytometric analysis of (A) Control and (B) Convolvulus pluricaulis of ETHE and Annexin V-FITC & PI double labeling were used to trigger apoptosis in Hep G2 cells. Results represent both panels indicate (Annexin +/PI −) early apoptosis in lower right quadrant/ (Q3), while (Annexin + /PI +) late apoptosis in the upper right quadrant/(Q2). The quadrant on lower left represents viable cells/(Q4). The upper left quadrant shows necrosis (Annexin −/PI +) (Q1)Back to article page
