The objectives of this thesis were (1) to evaluate molecular weight (M{sub r}) profiles of IGF-I and {sup 125}I-IGF-I; binding activity in pig serum; (2) to determine whether exogenous IGF-I partitions to IGFBPs in the circulation in pigs; (3) to purify and characterize the GH-dependent IGFBP from pig serum; (4) to assess the effects of the IGFBP on IGF-I action in vitro; (5) to establish a radioimmunoassay for the IGFBP; and (6) to measure IGFBP concentrations in serum from GH- and IGF-I-treated pigs.
