# Protein Data Bank

The Protein Data Bank is the single worldwide archive of structural data of biological macromolecules. Two entries are mirrored here in full, as mmCIF: 6M0J, the SARS-CoV-2 spike receptor-binding domain (RBD) bound to human ACE2 (X-ray, 2.45 Å), and 1IGT, an intact mouse IgG2a antibody (X-ray, 2.8 Å).

Two entries from the archive are mirrored here in full, so the structure
viewer on this card has something to open: `1igt.cif`, an intact IgG
antibody, and `6m0j.cif`, the SARS-CoV-2 spike receptor-binding domain bound
to human ACE2. Everything else about the PDB stays at the RCSB — follow the
source link.
