Figure 1

Spike/ACE2 binding in the presence of PPE, used at three concentrations, compared with control and antibody inhibitor AC384. The results are the averages of three independent experiments, expressed as percentages respect to control arbitrarily set as 100%. The error bars represent SDs and the asterisks indicate statistically significant values (*p-value is between 0.01 and 0.05; **0.001 and 0.01) according to T-test. ACE2, angiotensin-converting enzyme 2; PPE, pomegranate peel extract.
