Pegylated Rat Leptin Recombinant
| 目录号 | AP3573 |
|---|---|
| Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation | The protein was lyophilized from a concentrated (0.65mg/ml) solution with 0.003mM NaHCO3. |
| Protein biological activity | Pegylated Rat Leptin is capable of stimulatng proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor. Its in vitro activity is only slightly lower than the non-pegylated antagonist but in vivo it has profound weight reducing effect (as compared to the non-pegylated leptin), resulting mainly from reduced food intake. |
| Uniprot ACC# | P50596 |
| Purity | Greater than 99.0% as determined by:(a) Analysis by Gel-Filtration.(b) Analysis by SDS-PAGE. |
| Solubility | It is recommended to reconstitute the lyophilized pegylated Rat Leptin in sterile 0.4% NaHCO3 adjusted to pH-8.5, not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |
| Stability | Lyophilized Rat Leptin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Rat Leptin 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. |
| Source | Escherichia Coli. |
| Synonyms | OB Protein, Obesity Protein, OBS, Obesity factor. |
| Transportation method | Shipped at Room temp |
