From: Establishment of persistent infection with foot-and-mouth disease virus in BHK-21 cells
Western blot analysis for detection of viral proteins 3D and 3CD. Western blot analysis detected FMDV specific proteins 3D (viral RNA dependent RNA polymerase) and 3CD (a protein precursor consisting of two different proteins 3C and 3D) in BHK-Op48 cells and BHK-21 cells infected acutely (30 h.p.i., positive control). β-actin was included as control of protein loading and the number of cells.
