Figure 3From: Potent and persistent antibody responses against the receptor-binding domain of SARS-CoV spike protein in recovered patientsNeutralization of SARS pseudovirus infection by affinity-purified RBD-specific antibodies from the recovered SARS patients. Infection of 293T/ACE2 cells by SARS pseudovirus was determined in the presence of RBD-specific antibodies at a series of 2-fold dilutions, and percent neutralization was calculated for each sample.Back to article page
