Product Overview | |
| Name | Leptin Ovine, MTS |
|---|---|
| Description | |
| Leptin Ovine Recombinant, MTS tag | |
| Accession (Primary) | Q28603 |
| 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. | |
| Stability | |
| Lyophilized Leptin-Antagonist Quadruple Mutant Ovine Recombinant although stable at room temperature for several weeks, should be stored desiccated below -18°C. Upon reconstitution at > 0.1 LEP-qA mutant mg/ml and up to 2mg/ml 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. | |
| Purity | |
| Greater than 98.0% as determined by: (a) Gel filtration analysis. (b) Analysis by SDS-PAGE. | |
| Amino acid sequence | |
| The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Val-Pro-Ile-Arg. | |
| Biological Activity | |
| leptin qA is capable of inhibiting leptin-induced proliferation of BAF/3 cells stably transfected with the long form of ovine leptin receptor. It also inhibits various leptin effects in several in vitro bioassays. | |
| Solubility | |
| It is recommended to reconstitute the lyophilized Leptin-Antagonist Quadruple Mutant Ovine Recombinant in sterile 0.4% NaHCO3 adjusted to pH 8-9, not less than 100 µg/ml, which can then be further diluted to other aqueous solutions. | |
| Protein content | |
| Protein quantitation was carried out by UV spectroscopy at 280 nm using the absorbency value of 0.21 as the extinction coefficient for a 0.1% (1mg/ml) solution at pH 8.0. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics). | |
| Precautions | |
| Leptin Ovine, MTS is for research use only and not for use in diagnostic or therapeutic procedures. | |
