Extended Data Fig. 2: Titers of human serum concentrations used to detect anti-Cas9 antibodies with ELISA.
From: Identification of preexisting adaptive immunity to Cas9 proteins in humans

The same donor’s serum was applied at different concentrations by ELISA to detect antibodies against each antigen. The dilution of serum used to detect antibodies against each antigen is denoted above each graph.
