XL-MS and XRC comparison study for PD-1 and CTL-4

Three thereapeutic monoclonal antibody complexes were studied:
Ipilimumab/CTL-4
Nivolumab/PD-1
Nivolumab/PD-1

This study demonstrates strong correlation between the CovalX XL-MS method and existing X-ray cocrystal structure data for epitope mapping of three popular targets.
