SARS-CoV-2 binding dataset

Dataset of 104972 antibodies screened for binding the SARS-CoV-2 HR peptide, described in Engelhart et al. (2022), were obtained from Zenodo.

Average predicted logKD values were used for classifying sequences as binders and non-binders:

  • logKD<3 = binders
  • logKD>=4 = non-binders
  • logKD>=3 and logKD = ambiguous; removed.

Using these criteria, we have 51590 sequences remaining; these were stratified into an 80:10:10 ratio for training, test, validation, leading to:

  • 41787 sequences in training
  • 5159 sequences in validation
  • 4644 sequences in test
