Apoptosis induction by 5 kDa membrane filtrate in cultures persistently infected with DEN-2. A = Untreated naïve C6/36 control cells; B = C6/36 cells from a culture persistently infected with DEN-2; C = As in B except treated with the 5 kDa filtrate from the supernatant of C6/36 cells acutely infected with DEN-2 and showing nuclei with positive immunoflurescence (green) for the apoptosis marker YO-PRO-1 iodide.
