From: Modification of PCV-2 virulence by substitution of the genogroup motif of the capsid protein
Detection of the capsid after infection with supernatants of transfection of the four constructions. The capsid protein was detected with an anti-PCV-2b serum confirming that both parental and mutant clones were infectious. 1A) PK15 cells infected with PCV-2a, 1B) PK15 cells infected with PCV-2b, 1C) PK15 cells infected with PCV-2a/motif 2b, 1D) PK15 cells infected with PCV-2b/motif 2a and 1E) Mock-infected PK15 cells.
