| Abstract: | We probed the (immunochemical) relationship between the recently discovered growth hormone binding protein in human plasma and the growth hormone receptor using monoclonal and polyclonal antibodies raised against rabbit liver growth hormone receptor. The human binding protein was recognized by these antibodies; its immunological crossreactivity compared to the rabbit receptor was 1-2%. These data suggest a) that the binding protein and the receptor are structurally related and b) that rabbit and human growth hormone receptors share some but not all epitopes. |
