Effect of potential allergens on phosphatidylserine translocation in RBL-2H3 cells. RBL-2H3 cells were treated with different concentrations of test compounds for 30 min, and phosphatidylserine translocation was determined by an Annexin V-FITC fluos staining kit. Cells were photographed at ×630 magnification on an laser scanning confocal microscope. a vehicle, b C48/80 (30 μg/ml), c Rd (0.43 mM), d 20(S)-Rg3 (0.25 mM)
