Figure 2. Abundance of select zebrafish lens crystallins at different ages indicates a shift in expression between 6 weeks and 4 months. The proportional intensity of each crystallin spot was quantified by calculating its pixel density relative to actin. Error bars for the 10-day, 6-week, and 27-month time points indicate standard error of the mean (n=3). Multiple crystallins show a marked increase in expression between 6 weeks and 4 months of age.
