Leptin Antagonist Triple Mutant Ovine Recombinant, Pegylated
| 目录号 | AP3576 |
|---|---|
| Physical Appearance | 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 triple antagonist is capable of inhibiting leptin-induced proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor. Its in vitro activity is 6-8 fold lower than the non-pegylated antagonist but in vivo it has profound weight gain effect (as compared to the non-pegylated antagonist like in mouse leptin antagonists), resulting mainly from increased food intake. |
| Purity | Greater than 95.0% as determined by: (a) Gel filtration analysis. (b) Analysis by SDS-PAGE. |
| Solubility | It is recommended to reconstitute the lyophilized Leptin-Antagonist Triple Mutant Ovine Recombinant in sterile water or sterile 0.4% NaHCO3 adjusted to pH 8, not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |
| Stability | Lyophilized Leptin Antagonist Triple Mutant Ovine Recombinant although stable at room temperature for several weeks, should be stored desiccated below -18?C. Upon reconstitution at > 0.1 Lep-tA mutant mg/ml and up to 2mM and filter sterilization Leptin mutant can be stored at 4?C or even room temperature for several weeks making it suitable for long term infusion studies using osmotic pumps. At lower concentration addition of a carrier protein (0.1% HSA or BSA) is suggested. Please prevent freeze-thaw cycles. |
| Source | Escherichia coli. |
| Transportation method | Shipped at Room temp |
