Extended Data Fig. 7: FACS data from ICS and activation markers staining for donors 223–228.
From: Identification of preexisting adaptive immunity to Cas9 proteins in humans

Each individual donor number is shown at the top of each group of FACS plots. The red ‘+’ symbol below an antigen name indicates that a donor was considered positive for a cytokine response against that antigen by ICS. The red ‘−’ symbol below an antigen name indicates that a donor was considered negative for a cytokine response to that antigen by ICS.
