Figure 4. Effect of LASIK upon the synthesis of 35S-dermatan sulfate, 35S-keratan sulfate, and 35S-heparan sulfate by human corneal explants
Shown are the 35S-sulfate incorporation (A; cpm, mean±standard error, three determinations for each sample) and the ratio between LASIK and control (B). The identification of each glycosaminoglycan was based on a combination of agarose gel electrophoresis and enzymatic degradation with specific glycosaminoglycan lyases (chondroitinases, keratanase and heparitinase).
