Figure 2. Two-dimensional gel fragments showing differential expressed proteins between keratoconus patients and control subjects. Three of them were more expressed in control subjects and they were identified as zinc-α2-glycoprotein (ZAG), lactoferrin, and IGKC (immunoglobulin kappa chain). The other spot was more expressed in KC patients and it was identified as ZAG.
