  • Description
  • Placental growth hormone, or growth hormone variant (GH-V), is a member of the growth hormone gene family. Its physiologic role during pregnancy remains undefined. Although extensive work has been done characterizing the signaling pathways activated by hGH, the signaling pathways which are activated by GH-V have not been characterized. Human placental GH (hPGH) replaces pituitary GH during pregnancy. hPGH is correlated to serum IGF-I in normal pregnancies and in pregnancies complicated by fetoplacental disorders. Recombinant placental human GH-20K produced in E. coli is a single, non-glycosylated polypeptide chain of 177 amino acids and a molecular mass of 20,498 Dalton (predicted pI=8.2). PGH-20K-pl is devoid of lactogenic (prolactin receptor mediated) activity characteristic to pituitary GHs.

  • Activity
  • N/A
  • Endotoxin Level
  • Less than 1 EU/μg.
  • Formulation
  • Sterile-filtered, white, lyophilized (freeze-dried) powder. The protein was lyophilized from a concentrated (1 mg/ml) solution with 0.0045 mM NaHCO3 previously adjusted to pH 11.
  • Reconstitution
  • Please centrifuge product briefly before opening vial. The lyophilized protein should be reconstituted in sterile, 0.4% NaHCO3 adjusted to pH 11 to a concentration of 0.1 - 1.0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use.
  • Storage & Stability
  • The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted rHu GH-20K-pl should be used immediately or stored long- term in undiluted working aliquots at -20°C. For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.
