Cat#:RP-5024H;Product Name:Recombinant Human pGH 22kDa Protein;Synonym:GHL, GHV, GH-V, hGH-V, PGH.;Description:Placental HGH 22kDa Recombinant produced in E.coli is a single, non-glycosylated, polypeptide chain containing 192 amino acids and having a molecular mass of 22367 Dalton. Predicted pI=7.80. Placental Growth Hormone has dimished lactogenic (prolactin receptor mediated) activity characteristic to pituitary GHs. GH Placental Protein is purified by proprietary chromatographic techniques.;Source:E.coli;AA Sequence:The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Phe-Pro-Thr-Ile.;Purity:Greater than 98.0% as determined by: (a) Analysis by SEC-HPLC. (b) Analysis by SDS-PAGE.;Formulation:The protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3 previously adjusted pH 8-9.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized Placental HGH in 0.4% NaHCO3or water adjusted to pH 9, not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized GH placental although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution and filter sterilization HGH placental can be stored at 4°C for up to 4 weeks. For long term storage and more diluted solutions it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.;
