PGH 20kDa Human

• Description:

  Growth Hormone Placental 20kDa Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 177 amino acids and having a molecular mass of 20498 Dalton. Predicted pI=8.20. Growth Hormone 20K placental is devoid of lactogenic (prolactin receptor mediated) activity characteristic to pituitary GHs.

• Swiss Prot:

  O14643

• Source:

  Escherichia Coli.

• Buffer:

  PGH 20kDa was lyophilized from a concentrated (1 mg/mL) solution with045mM NaHCO3 previously adjusted pH 11.

• Storage Conditions:

  Lyophilized Growth Hormone 20K Placental although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution and filter sterilization GH 20K pl 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) .

• Sequence Similarities:

  The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Phe-Pro-Thr-Ile.
