Knowledge regarding the insulin-like growth factor (IGF) system and the methods for the detection and quantitation of IGF binding proteins (IGFBPs) is greater for the human species than for other animal species. This is mainly because antibodies specifically raised against nonhuman IGFBPs are rarely commercially available. We aimed to investigate which of the antibodies directed against human IGFBPs could be used for the detection of IGFBPs present in other species. We used commercially available antibodies, raised against human IGFBP-1 through IGFBP-4, in order to recognize the corresponding IGFBPs in the sera of different animal species: human, bovine, equine, porcine, ovine, …
