Th1 Response

Parathyroid hormone is the most important endocrine regulator of calcium and phosphorus concentration in extracellular fluid. This hormone is secreted from cells of the parathyroid glands and finds its major target cells in bone and kidney. Another hormone, parathyroid hormone-related protein, binds to the same receptor as parathyroid hormone and has major effects on development. Like most other protein hormones, parathyroid hormone is synthesized as a preprohormone. After intracellular processing, the mature hormone is packaged within the Golgi into secretory vesicles, the secreted into blood by exocytosis. Parathyroid hormone is secreted as a linear protein of 84 amino acids.

Hormone releasing factors and releasing hormones are  signaling molecules produced by glands in multicellular organisms. The glands that secrete Luteinizing hormones LHRG and LH, FSH comprise the endocrine signaling system. The term growth hormone releasing hormone GHRH is sometimes extended to include chemicals produced by cells that affect the same cell (autocrine or intracrine signaling) or nearby cells (paracrine signaling). Human recombinant LHRG and GHRH are produced in E. coli or in yeast cells.

Always centrifuge tubes before opening. Do not mix by vortex or pipetting.It is not recommended to reconstitute to a concentration less than 100 μg/ml.Dissolve the lyophilized protein in ddH2O.Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months.

Lyophilized from a 0.2 μm filtered solution of 10mM HAc-NaAc, 150mM NaCl, 5% Mannitol, pH 4.0.

Less than 0.1 ng/µg (1 IEU/µg) as determined by LAL test.

Greater than 95% as determined by reducing SDS-PAGE.
