Product Overview | |
| Name | Placental Lactogen Caprine |
|---|---|
| Description | |
| Placental Lactogen Caprine Recombinant | |
| Synonyms | |
| Chorionic Somatomammotropin Hormone 1, CSH1, Choriomammotropin, Lactogen, CSH2, PL, CSA, CSMT, FLJ75407. | |
| Introduction | |
| Placental Lactogen is a polypeptide hormone that is produced by the Syncytiotrophoblasts of the Placenta, also known as chorionic somatomammotropin. It has both GH 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 ins. antagonist. Placental Lactogen Bovine 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 Human 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 99.0% as determined by: (a) Analysis by Gel Filtration. (b) Analysis by SDS-PAGE. | |
| Amino acid sequence | |
| The sequence of the first 6 N-terminal amino acids was determined and was found to be Ala-Val-Gln-Thr-Val-Pro. | |
| Biological Activity | |
| Placental Lactogen Human is biologically active as evidenced by inducing proliferation of Nb2 cells. | |
| Solubility | |
| It is recommended to reconstitute the lyophilized Placental Lactogen in sterile water or 0.4% NaHCO3 adjusted to pH 8-9, not less than 100 µg/ml, which can then be further diluted to other aqueous solutions, preferably in presence of carrier protein. | |
| Protein content | |
| UV spectroscopy at 280 nm using the absorbency value of 0.73 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the DNAman computer analysis program of protein sequences. | |
| Precautions | |
| Placental Lactogen Caprine is for research use only and not for use in diagnostic or therapeutic procedures. | |
