Figure 3From: Feline aminopeptidase N is not a functional receptor for avian infectious bronchitis virusIBV strain Mass41 can infect feline cells at low levels. A & B) Primary CK or CRFK, cells were infected with IBV_Mass41 for 12 h and labeled with monoclonal α-S1(15:88) antibody to detect viral infection in three independent experiments. Viral infectivity was determined by counting >300 cells. Error bars represent the standard deviation from the mean.Back to article page
