Antibody that specifically binds to insulin-like growth factor 1

The present invention, as known for human insulin-like growth factor 1 precursor (SEQ ID NO: 1) relates to an isolated antibody that specifically binds to an epitope contained in the amino acid stretch in the range of amino acids 76 to amino acid 84. New antibodies, even when the insulin-like growth factor 2 closely related are present in large excess concentrations, to allow the high sensitivity and specific detection of insulin-like growth factor 1, very it is useful. Detection of insulin growth factor 1 can be, for example, a body fluid sample in.
