Leptin Antagonist Triple Mutant Mouse Recombinant is a single non-glycosilated polypeptide chain containing 146 amino and additional Ala at N-terminus acids and having a molecular mass of ~ 16 kDa.The Mouse Leptin antagonist was mutated, resulting in L39A/D40A/F41A mutant.The Mouse Leptin antagonist is bound to 20 kDa mono-PEG at N-terminus, resulting in 35.6 kDa. The Mouse Leptin triple anatagonist runs as a 48 kDa.Leptin Antagonist Triple Mutant Mouse Recombinant was purified by proprietary chromatographic techniques.

产品描述 Description
产品文档 Product Documents
Purity:>98%
Product Data
Purity
Greater than 99.0% as determined by:(a) Gel filtration analysis.(b) Analysis by SDS-PAGE.
Source
Escherichia coli.
Physical Appearance
White lyophilized (freeze-dried) powder.
Shipping Condition
Shipped at Room temp.
Solubility
It is recommended to reconstitute the lyophilized Leptin Antagonist Triple Mutant Mouse Recombinant in sterile water or sterile 0.4% NaHCO3 adjusted to pH 8-9, not less than 100µg/ml, which can then be further diluted with other aqueous solutions.
Stability
Lyophilized Leptin Antagonist Triple Mutant Mouse Recombinant 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 2mM 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
Leptin Antagonist Triple Mutant Mouse Recombinant half-life in circulation after SC injection was over 20 hours.Leptin Antagonist Triple Mutant Mouse Recombinant is capable of inhibiting leptin-induced proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor. Leptin Antagonist Triple Mutant Mouse Recombinant in vitro activity is 5-6 fold lower than the non-pegylated antagonist, though in vivo it has profound weight gain effect (as compared to the non-pegylated antagonist), resulting mainly from increased food intake.
Formulation
The Mouse Leptin triple anatagonist was lyophilized from a concentrated (0.65mg/ml) solution with 0.003mM NaHCO3.
