FIG. 2.
Detection of fibrillarin by indirect immunofluorescence in mock-transfected Vero cells (A to C) and HeLa cells (D to E) and in mock-infected chicken kidney cells (F). Fibrillarin was detected with anti-fibrillarin (human) mouse monoclonal antibody (green). The nucleus was visualized by staining with PI (B, C, and E). Colocalization when it occurs is shown in yellow. Magnifications: A to C, E, and F, ×60; D, ×15.
