A radioimmunoassay for rat serum parathyroid hormone using N-terminal of PTH
Endocrinologia Japonica
|April 1, 1975
Abstract:
Partially purified bovine parathyroid hormone (PTH) produced two kinds of antisera, GP-100 reacting with 125I-labeled bovine PTH (b-PTH 1-84) alone and GP-M reacting with 125I-labeled synthetic N-terminal portion of bovine PTH (b-PTH 1-34) as well as b-PTH 1-84. Rat serum PTH reacted with the latter but not in the former, suggesting a similarity to b-PTH 1-34. Rat serum PTH became undetectable after parathyroidectomy, and increased after Na2-EDTA injection and following renal injury with sodium sulfacetylthiazole.
