Blockade assay of the SARS‐CoV‐2‐RBD/ACE2 and SARS‐CoV‐1‐RBD/ACE2 interactions by anti‐ACE2 peptides. Blocking efficiency and IC50 of a) the anti‐ACE2 antibody, b) CPS4 peptide, c) CPS13 peptide, and d) the dimer of CPS4 peptide against the SARS‐CoV‐2‐RBD/ACE2 interaction. Blocking efficiency and IC50 of e) the CPS4 peptide and f) CPS4 dimer against the SARS‐CoV‐1‐RBD/ACE2 interaction. All results are presented as the mean ± SD (n = 3).
