Recombinant human Growth Hormone 20 kDa Pituitary produced in
E. coli is a single, non-glycosylated, polypeptide chain containing 177 amino acids and having a molecular mass of 20.3 kDa. HGH-20 kDa is purified by proprietary chromatographic techniques.
Synonyms: GH1, GH, GHN, GH-N, hGH-N, Pituitary growth hormone, Growth hormone 1, Somatotropin.
Formulation: HGH-20K was lyophilized from a concentrated (1mg/ml) solution with 0.0045 mM NaHCO3 previously adjusted to pH 10.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
Purity: Greater than 98% as determined by: (a) Analysis by SEC-HPLC. (b) Analysis by SDS-PAGE.
Source:Escherichia coli. Amino acid sequence: The sequence of the first five N-terminal amino acids was determined and was found to be Ala-pH e-Pro-Thr-Ile.
Uniprot ACC number: P01241
Transportation method: Shipped at room temperature.
Stability: Lyophilized Pituitary Growth Hormone-20K although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution and filter sterilization GH-20K 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.
Solubility: It is recommended to reconstitute the lyophilized Growth Hormone Pituitary in 0.4% NaHCO3 adjusted to pH 10, not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
