Figure 5. Spatial expression of osteonectin in normal lens epithelia

Ethidium bromide stained gels showing the relative levels of osteonectin (419 bp), [alpha]B-crystallin (547 bp) and GAPDH (600 bp) detected by 33 RT-PCR cycles using 100 ng RNA from pooled whole (W, lane 1) or central (C, lane 2) epithelial sections.
