Human EBV protein and CMV peptide pool of pp65 sequence consisting of 138 peptides (15 mers with 11 amino acid overlaps) was purchased from JPT Peptide Technologies (Berlin, Germany).
All patients were DSA-free with a calculated panel reactive antibody (PRA) ≤20% at enrollment. Patient samples were assessed for donor-specific alloantibody post-transplantation as described previously (18 (link)).
