Figure Lengend Snippet: Brefeldin A inhibits DPV infection in DEF cells . (A-C) DEF cells were infected with DPV-CHv-GFP at 1 MOI for 1 h, then treated with different concentrations of Brefeldin A, DMSO was added as control. The viral fluorescence spots were photographed under fluorescence microscope at 24 hours post infection (hpi). The scale bar is 100 µm (A). The infected cells were collected and the copy number of the DPV gene was detected by Q-PCR (B), and the cell supernatant was collected to determine the virus titer TCID 50 (C). (D) DEF cells were treated with different concentrations of Brefeldin A for 48 h, and then the cell viability was determined using the CCK-8 cell viability assay kit.
Article Snippet: Brefeldin A (BFA) was purchased from MedChemExpress and diluted with dimethyl sulfoxide (DMSO), with a purity of 99.82%.
