abstract：:Binding of PTH to purified canine renal cortical membranes was investigated using biologically active radioiodinated bovine PTH-(1-84) [bPTH-(1-84)] as radioligand. PTH-(1-84) is thought to be the major circulating form of bioactive PTH, but oxidative inactivation upon iodination has prevented its use as a radioligand...
