Cat#:RP-5303H;Product Name:Recombinant Human PTH (1-84) N15 Protein;Synonym:Parathyrin, PTH, Parathormone.;Description:PTH (1-84) N15 Protein produced in E.coli is a single, non-glycosylated polypeptide chain containing 84 amino acids and having a molecular mass of 9550 Dalton labeled by the stable isotope N15. The PTH (1-84) N15 is purified by proprietary chromatographic techniques.;Source:E.coli;AA Sequence:SVSEIQLMHN LGKHLNSMER VEWLRKKLQD VHNFVALGAP LAPRDAGSQR PRKKEDNVLV ESHEKSLGEA DKADVNVLTK AKSQ.;Purity:Greater than 97.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.;Bioactivity:The activity calculated by UMR106 cell/cAMP method corresponding to a specific activity of 9,000 Units/mg.;Formulation:PTH (1-84) N15 protein was lyophilized from a 0.2µm filtered concentrated solution in 1xPBS, pH 7.4.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized Parathormone in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.;Storage: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.;
