Table 2 - IgStrand: A universal residue numbering scheme for the immunoglobulin-fold (Ig-fold) to study Ig-proteomes and Ig-interactomes

VH:VL interactions of Fabs binding SARS-CoV-2 spike protein (70% cutoff). Red numbers represent symmetric contacts. Bold contacts represent highly conserved hydrogen bonding contacts. Shaded cells represent five highly conserved contacts (90% cutoff) shared between SARS-CoV-2 antigen binding dataset and diverse antigen binding dataset (Table B in S1 Text).
