Figure 4. Osteonectin expression in six individual epithelia isolated from cataractous lenses

Ethidium bromide stained gels showing the relative levels of osteonectin detected by 35 RT-PCR cycles in 50 ng RNA in epithelia dissected from six cataractous lenses. The type of each cataractous epithelia is listed above each lane (nuc-nuclear; mix-mixed). Also indicated are the ages of the cataractous donors. Arrows indicate the 547 bp [alpha]B-crystallin control product and the 419 bp osteonectin product.
