Six different reaction patterns were shown by crossing ELISA using a group of McAb (C1,C2,C3,J1,J2,and J3) against three structural proteins of IBV and six IBV standard strains of different serotypes (Gray, Connecticut, Hotle, T, M41 and Arkansas).

• 针对IBV三种结构蛋白的一组单抗(C1、C2、C3、J1、J2、J3)和6个不同血清型的IBV标准株(Gray株、Connecticut株、Holte株、T株、M41株、Arkansas株)进行交叉ELISA试验,显示了6种不同的反应模式;
