Figure 1. BF proteins are found in the mouse lens epithelium. A: Sagittal paraffin section of mouse lens labeled with antibodies to CP49 (green channel) and 4',6-diamidino-2-phenylindole (DAPI; blue channel). The image is oriented so that the anterior pole is at the 12 o’clock position. White arrows identify three of more than 20 examples of the CP49-reactive structure in the lens epithelium (scale bar = 100 μm). B: Higher magnification view of the lens epithelium labeled as in A, with a good example of this CP49 reactive structure highlighted by the white arrow (bar = 20 μm).
