Abstract
A sensitive sandwich enzyme immunoassay for tyrosine hydroxylase (TH) from bovine and human adrenals has been developed. Anti-TH antibody was prepared from bovine adrenal TH. The assay system consisted of an antibody F(ab′) 2 immobilized on polystyrene beads as a solid phase and of β- d-galactosidase-conjugated antibody. This method was highly sensitive and specific for the assay of TH. Human adrenal TH level was determined by similar sensitivity as bovine adrenal TH, suggesting the presence of common antigenic sites between human and bovine adrenal enzymes. The presence of inactive or less active forms of TH in human adrenals was revealed by purification of the enzyme and monitoring with this enzyme immunoassay as well as with enzyme activity assay.
