Description
Placental Lactogen Ovine Recombinant, is a single polypeptide chain containing 199 amino acids and an additional Ala at the N-terminus having a molecular mass of 23 kDa. Placental Lactogen Recombinant is purified by proprietary chromatographic techniques.
Additional Information
IntroductionPlacental Lactogen is a polypeptide hormone that is produced by the Syncytiotrophoblasts of the Placenta, also known as chorionic somatomammotropin. It has both Growth Hormone and Prolactin activities on growth, lactation, and luteal steroid production. In women, placental lactogen secretion begins soon after implantation and increases to 1 g or more a day in late pregnancy. Placental lactogen is also an insulin antagonist.Placental Lactogen Ovine is also capable of activating human and other heterologous GH receptors but not ruminat GH receptors.
SynonymsChorionic Somatomammotropin Hormone 1, CSH1, CS-1, hCS, PL.
SourceEscherichia Coli.
Physical AppearanceSterile Filtered White lyophilized (freeze-dried) powder.
FormulationThe protein was lyophilized from a concentrated (1mg/ml) solution with 0.02-0.03% NaHCO3.
SolubilityIt is recommended to reconstitute the lyophilized Placental Lactogen in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
StabilityLyophilized Placental Lactogen Ovine Recombinant althoµgh stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Placental Lactogen 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.
