Immunofluorescence staining of HEp-2 cells was performed with tumor Igs from
FL15, FL26, MCL32, and MM63, and colocalization with anti-vimentin V9 mAb was
determined. Each column represents staining with one tumor Ig. Top to bottom: V9
mAb alone (green), tumor Ig (red), V9 mAb and tumor Ig overlay, and
colocalization pixels.
