Figure 3. CAT expression with various promoter constructs
The X-axis indicates relative promoter activity as indicated by CAT expression. The Y-axis indicates the promoter fragment size contained in the CAT reporter construct. A: CAT activity results obtained from primary chick lens epithelial cell cultures. B: CAT activity results obtained from primary chick fibroblast cultures. All results are shown as a percent of the SV40 control promoter activity.
