From: Role of CD151, A tetraspanin, in porcine reproductive and respiratory syndrome virus infection
Transfection of simian CD151 into BHK-21 cells. To detect the presence of PRRSV in simian CD151-transfected BHK-21 cells, immunohistochemical staining was performed using SR-30, a MAb against PRRSV nucleocapsid protein. (A) Simian CD151-untransfected BHK-21 cells, and (B) Simian CD151-transfected BHK-21 cells. The presence of PRRSV is shown by DAB substrate in brown color.
