Data reported in the Zeng study were; sample collagen data and O.
niloticus collagen subunit a1 had a match score of 93, coverage of
2%, and contained 3 matching peptides; sample collagen data and
O. niloticus collagen subunit a2 had a match score of 117, coverage
rate of 2%, and contained 3 matching peptides. Therefore, we
concluded the SCC and SKC to be O. niloticus type I collagen.
