SYNONYMS
PTH/PTHrP receptor antagonist, PTHrP analog, PTHR, MGC138426, MGC138452.INTRODUCTION
Polypeptide hormones secreted by the parathyroid glands, which promote release of calcium from bone to extracellular fluid by activating osteoblasts and inhibiting osteoclasts, indirectly promote increased intestinal absorption of calcium, and promote renal tubular reabsorption of calcium and increased renal excretion of phosphates. It is a major regulator of bone metabolism. Secretion of parathyroid hormone increases when the level of calcium in the extracellular fluid is low. Its action is opposed by calcitonin.PTH (7-34), which is a PTH/PTHrP receptor antagonist, can stimulate hair growth and epidermal proliferation in mice.
DESCRIPTION
Parathyroid Hormone Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 28 amino acids and having a molecular mass of 3380 Dalton.The PTH is purified by proprietary chromatographic techniques.
SOURCE
Escherichia Coli.PHYSICAL APPEARANCE
Sterile Filtered White lyophilized (freeze-dried) powder.FORMULATION
The protein (1 mg/ml) was lyophilized after extensive dialyses against 20mM PBS pH-7.0 and 150mM NaCl.SOLUBILITY
It is recommended to reconstitute the lyophilized PTH in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.STABILITY
Lyophilized Parathyrin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution PTH should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
PURITY
Greater than 97.0% as determined by:(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
AMINO ACID SEQUENCE
LMHNLGKHLN SMERVEWLRK KLQDVHNF.BIOLOGICAL ACTIVITY
The activity calculated by UMR106 cell/cAMP method corresponding to a specific activity of 10,000 Units/mg.USAGE

文献和实验Transmigration of Human CD34+ Cells
to understand the mechanisms responsible for their homing and/or mobilization. In this chapter, we will describe the methodology utilized in our laboratory to evaluate migration of human CD34+ cells that contain HSC.
Generation of TransgenicT Cells from Human CD34+Cord Blood Cells
Hematopoietic stem cells (HSCs), progenitor cells capable of generating all peripheral blood cell lineages, are believed not to express lineage markers (Lin) found on the latter, nor CD38, but may or may not express CD34. Besides HSCs
Short-Term Culture of Human CD34+ Cells for Lentiviral Gene Transfer
biological properties of HSCs. We describe here methods for short-term ex vivo culture and gene transfer into human HSCs. Cord blood-derived HSC gene transfer can be tuned to limit the average level of vector integration or instead to maximize
