Figure 1. MALDI mass spectra of αA-crystallin truncation in bovine and rabbit lens. Extracted representative mass spectra from the outer cortex (A, D), middle cortex (B, E), and outer nucleus (C, F) of bovine (A-C) and rabbit (D-F) lenses are shown. Degradation products increased toward the nucleus of both species, although higher mass degradation products are more prominent in the rabbit lenses than in the bovine lenses.
