IGF binding proteins (IGFBPs) are important biomarkers for diagnostics and treatment studies. In different physiological conditions IGFBPs are actively degraded by specific proteases. Due to the detection of intact and fragmented IGFBPs, ELISA or RIA techniques may generate biased IGFBP-data. We thus developed quantitative western ligand blotting for comprehensive monitoring of intact IGFBPs and IGFBP-profiles in biological fluids of vertebrates. The dynamic range for each IGF...
