Effect of penta-O-galloyl-β-d-glucose (PGG) on phosphatidylserine exposure in the presence and absence of extracellular Ca²⁺. Arithmetic means ± SEM (n = 8) of the percentage of annexin V binding erythrocytes after a 48-h treatment with Ringer solution without (white bar) or with (black bars) 25 µM penta-O-galloyl-β-d-glucose in the presence (left bars, Plus Calcium) and absence (right bars, Minus Calcium) of calcium. *** (p < 0.001) indicates significant difference from the absence of penta-O-galloyl-β-d-glucose (ANOVA), ## (p < 0.01) indicates significant difference from the respective values in the presence of Ca²⁺ (ANOVA).
