This track shows epitopes that were validated in published studies, mostly from the SARS 2003 outbreak.
The epitope sequences were collected by Nerli et al, partially from the IEDB database, partially from the original literature. The details page shows how similar the SARS-Cov-2 epitope is to the SARS epitope.
The raw data can be explored interactively with the Table Browser, or combined with other datasets in the Data Integrator tool.
