Assay of IGFBP complex

摘要

A method of assaying the growth hormone status of an individual by immuno-assay for the 150 KDa Insulin-like Growth Factor ternary complex (IGF/IGFBP-3/ALS). Alternatively, a binary complex may be assayed. The method involves capturing the IGFBP complex with a first antibody coupled to a solid phase and detecting the complex with a second antibody coupled to a label. A set of monoclonal and polyclonal antibodies usefutl for the assay is also provided.
