Fig. 1. Colocalization of lamin A with RNA splicing factors. Methanol-fixed C2C12 myoblasts were labeled with mAb LA-2H10 and antibodies to (A) SC-35 or (B) U5-116 kDa. Confocal overlays of the doubly stained cells are shown in the merged panel, where the yellow color highlights structures stained by both antibodies in a single optical section of 0.5 µm. Scale bar: 10 µm.
