Abstract
Intact, biologically active parathyroid hormone (1-84) extracted from horse parathyroid glands was detected by heterologous amino terminal radioimmunoassays and heterologous carboxyl terminal radioimmunoassay using antibovine parathyroid hormone antibodies. The immunochemical behavior of horse parathyroid hormone suggests that this hormone possesses a 1 −34 amino terminal portion very similar to that of the human one and structural differences in the 53-84 portion from those of the three known parathyroid hormones.
