A cloned LLC-PK1 cell line showed increased ASFV susceptibility. A ASFV infection in different swine-derived cell lines. B ASFV infectivity in parental LLC-PK1 or its subclones were examined by IFA with a monoclonal antibody against the ASFV p30 protein. Scale bar = 200 μm. C ASFV infectivity in parental LLC-PK1 or its subclones were examined by qPCR. D The number of parental LLC-PK1 cells and Clone 5 (PK1-C5) monoclonal cells at different time points. Scale bar = 200 μm.
