Leptin Salamander Recombinant
| 目录号 | AP3577 |
|---|---|
| Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation | The Salamander Leptin was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3. |
| Protein biological activity | By inducing proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor. Its activity in that test is similar to that of mouse leptin (see Salomon et al (2006) Protein Expression and Purifcation 47, 128?C136). |
| Amino acid sequence | The sequence of the ten N-terminal amino acids was determined and was found to be Ala-Ile-Met-Val-Asp-Gln-Leu-Arg-Met-Asp. |
| 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 Salamander Leptin in sterile 0.4% NaHCO3 pH-9 not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |
| Stability | Lyophilized Salamander Leptin although stable at room temperature for 3 weeks, should be stored desiccated below -18?C. Upon reconstitution 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, Leptin. |
| Transportation method | Shipped at Room temp |
