FIGURE 1.

Flow cytometry of severe acute respiratory syndrome coronavirus 2 receptor binding domain binding to human islet cells. (a) Representative histogram plots of unstained, control‐green fluorescent protein (GFP) and receptor binding domain (RBD)‐GFP, both diluted 1:2000. (b) Mean fluorescence intensity (MFI) of GFP fluorescence of control‐GFP or RBD‐GFP binding to human islet cells at dilutions from 1:100 to 1:2000. Data show mean + SEM for n = 3 independent human islets donors. Individual data points for each donor are shown. ^** p < 0.005, unpaired t test
