Tissue-specific hydroxylation patterns in type I collagen from bovine eye tissues. LC-MS profiles of in-gel trypsin digests of the α1(I) collagen chains from bovine sclera and cornea. A, MS profile of α1(I) from bovine cornea reveals no 3-hydroxylation at the (GPP)n. B, MS profile of the α1-chain from bovine scleral type I collagen reveals a similar hydroxylation to that observed in mouse tendon and sclera. The trypsin digested peptide is shown with P# indicating 3Hyp and P* indicating 4Hyp.
