| Purity | Greater than 98.0% as determined by:(a) Gel filtration analysis.(b) Analysis by SDS-PAGE. | Source | Escherichia coli. |
| Phycical Appearance | White lyophilized (freeze-dried) powder. | Shipping Condition | Shipped at Room temp. |
| 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. | ||
| Solubility | It is recommended to reconstitute the lyophilized Leptin Antagonist Quadruple Mutant in sterile 0.4% NaHCO3 adjusted to pH 8-9, not less than 100µg/ml, which can then be further diluted to other aqueous solutions. | ||
| Stability | Lyophilized Leptin Antagonist Quadruple Mutant although 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 suggested. Please prevent freeze-thaw cycles. | ||
| Biological Activity | ProSpecбпs 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. | ||
| Formulation | The protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3. | ||
