Product Overview | |
| Name | Placental Lactogen Human |
|---|---|
| Description | |
| Placental Lactogen Human Recombinant | |
| Accession (Primary) | P01243 |
| Synonyms | |
| Chorionic Somatomammotropin Hormone 1, CSH1, CS-1, hCS, PL. | |
| Introduction | |
| Placental 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. | |
| Source | |
| Escherichia Coli. | |
| Physical Appearance | |
| Sterile Filtered White lyophilized (freeze-dried) powder. | |
| Formulation | |
| The protein was lyophilized from a concentrated (1mg/ml) solution with 0.02-0.03% NaHCO3. | |
| Stability | |
| Lyophilized Placental Lactogen Ovine Recombinant although 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. | |
| Purity | |
| Greater than 98.0% as determined by: (a) Analysis by SEC-HPLC. (b) Analysis by SDS-PAGE. | |
| Amino acid sequence | |
| The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Gln-His-Pro-Pro. | |
| Biological Activity | |
| Placental Lactogen Ovine is biologically active as evidenced by inducing proliferation of Nb2 cells. | |
| Solubility | |
| It is recommended to reconstitute the lyophilized Placental Lactogen in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions. | |
| Protein content | |
| UV spectroscopy at 280 nm using the absorbency value of 0.85 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics). | |
| Precautions | |
| Placental Lactogen Human is for research use only and not for use in diagnostic or therapeutic procedures. | |
