This tag-free fragment spanning residues 38–65 of human PTH delivers validated bioactivity exceeding 1.0 × 10⁴ IU/mg as measured by cAMP induction in UMR106 cells, confirming robust PTH1R engagement suitable for receptor binding assays, competition studies, and downstream cAMP signaling experiments. The partial sequence corresponds to a functionally critical region of parathyroid hormone, enabling focused structure-function investigations of receptor interaction domains without interference from fusion tags. Endotoxin levels below 1.0 EU/μg combined with purity greater than 97% by SDS-PAGE satisfy the criteria typically required for in vivo pharmacology models of calcium homeostasis and metabolic bone disease, as well as for use as a calibration standard in immunoassays. This E. coli-expressed protein provides a suitable basis for antibody development campaigns targeting the mid-region epitope of mature PTH.
