Antigenicity of the peplomer protein of infectious bronchitis virus
Molecular Immunology, 1989 To study the antigenic structure of the peplomer protein of the avian coronavirus infectious bronchitis virus, fragments from the peplomer gene were generated by restriction-enzyme cleavage or by limited DNase digestion and inserted in the Escherichia coli expression plasmid pEX (Stanley and Luzio, 1984). The antigenicity of the expression products was

Heterogeneity of infectious bronchitis virus grown in eggs [PDF]
Archives of Virology, 1976 Egg-grown infectious bronchitis virus, strain Beaudette, was concentrated and centrifuged on sucrose density gradients to separate the virus into five peaks with densities of 1.144, 1.160, 1.172, 1.191 and 1.218 g/cm3. All peaks retained infectivity, complement fixation activity and were labelled with 3H-uridine.
