Evaluation of type I and II collagen biomarkers for the detection of joint pathology in elephants

The first objective of this trial was to evaluate whether biomarkers for type I and type II collagen were detectable in elephant serum samples. Two commercially available enzyme-linked immunoabsorbent (ELISA) assays for the detection of the crosslinking telopeptides of type I collagen (CTX-I) and type II collagen (CTX-II) were validated for use with elephant sera. The second objective was to...
