MHC-I complex formation of the chimeric class I molecule HHP (HLA-A*11:01 (α1α2), SLA-1*0401 (α3)) with a known HLA-A*11:01-binding peptide (KVFPYALINK), and human (open squares) versus porcine β2m (filled circles). The affinity of HHP to porcine and human β2m was determined as 0.774 nM (95% confidence interval, 0.630 to 0.951) and 1.19 nM (95% confidence interval, 0.958 to 1.47), respectively
