LyeTx I b does not alter the morphology of ARPE-19 cells and maintains cell viability above 50%. a Figure shows ARPE-19 cells in the absence or presence of LyeTx I b (2.89 μM) indicating a healthy culture. b Graph shows cells not exposed (ARPE-19) or exposed to LyeTx I b (0.36, 0.54, 0.72, 2.89, 4.34 or 9.06 μM). Data represent the means ± SEM of three independent experiments. * indicates significant difference as compared to ARPE-19 (p < 0.05). Abbreviations: SEM, standard error of the mean. Cells were visualized (5X) using a Zeiss microscope (Axio Imager M2, Zeiss) and images were captured with a digital camera coupled to it
