| Synonyms | NULL |
| Source | Escherichia coli. |
| Physical Appearance | White lyophilized (freeze-dried) powder. |
| Formulation | The protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3. |
| Solubility | It is recommended to reconstitute the lyophilized Leptin Antagonist Quadruple Mutant in sterile 0.4% NaHCO3adjusted to pH 8-9, not less than 100 |
| Stability | Lyophilized Leptin Antagonist Quadruple Mutant althoµgh stable at room temperature for several weeks, should be stored desiccated below -18°C. Upon reconstitution at > 0.1 Leptin mutant mg/ml and up to 2 mM and filter sterilization LEP 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 sµggested. Please prevent freeze-thaw cycles. |
| Amino Acid Sequence | The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Val-Pro-Ile-Gln. |
| Purity | Greater than 98.0% as determined by:(a) Gel filtration analysis.(b) Analysis by SDS-PAGE. |
| Biological Activity | NeoBiolab’s Leptin Quadruple Antagonist Mutant is capable of inhibiting leptin-induced proliferation of BAF/3 cells stably transected with the long form of human Leptin receptor. It also inhibits various Leptin effects in several in vitro bioassays. |
| Usage | NeoBiolab's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drµgs, agricultural or pesticidal products, food additives or household chemicals. |
