However, based on data obtained using monoclonal antibodies (Mab), there appears to be at least three to ®ve neutralizing, conformationally dependent epitopes on the S1 subunit in different IBV strains [13, 15, 20] . Mab-neutralization-resistant (NR) mutants have been used to identify amino acids (AA) involved in conformationally dependent epitopes in the spike protein of IBV [5, 12] . Based on AA substitutions in Mab-NR mutants, the S1 subunit was divided into three regions associated with neutralizing, conformationally dependent epitopes. In previous research, AA substitutions in IBV Mab-NR mutants were divided into three regions associated with neutralizing epitopes. ./cache/cord-004812-ikco4h5k.txt ./txt/cord-004812-ikco4h5k.txt
