PTH 1-34 (teriparatide) is the biologically active N-terminal 34-amino-acid fragment of parathyroid hormone, acting on PTH1 receptors to regulate calcium and phosphate metabolism and bone remodeling in research models. It is supplied as a high-purity white lyophilized powder at >=99% HPLC purity in sealed vials, offering good stability and easy reconstitution. It is widely used in bone-biology research, osteoporosis mechanism studies, calcium-regulation experiments and cell-based assays on osteoblast and osteoclast function. All lots pass strict quality verification and lot-specific certificates can be provided on request. Keep unopened material sealed at 2-8 degree C away from light and moisture; store at -20 degree C for longer periods and avoid repeated freezing. We accept small trial and large bulk orders and provide OEM, private-label and neutral discreet-packaging services with global delivery. Laboratory research use only.
