Description
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.
Additional Information
IntroductionNULL
SynonymsNULL
SourceEscherichia coli.
Physical AppearanceWhite lyophilized (freeze-dried) powder.
FormulationThe Mouse Leptin triple anatagonist was lyophilized from a concentrated (0.65mg/ml) solution with 0.003mM NaHCO3.
SolubilityIt is recommended to reconstitute the lyophilized Leptin Antagonist Triple Mutant Mouse Recombinant in sterile water or sterile 0.4% NaHCO3adjusted to pH 8-9, not less than 100
StabilityLyophilized Leptin Antagonist Triple Mutant Mouse Recombinant 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 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 sµggested.Please prevent freeze-thaw cycles.
PurityGreater than 99.0% as determined by:(a) Gel filtration analysis.(b) Analysis by SDS-PAGE.
Biological ActivityLeptin 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, thoµgh in vivo it has profound weight gain effect (as compared to the non-pegylated antagonist), resulting mainly from increased food intake.
