Catalog Number orb426845
ReactivityHuman
ConjugationUnconjugated
Target Leptin tA
Product Properties
Form/Appearance White lyophilized (freeze-dried) powder.
The protein was lyophilized from a concentrated (0.65mg/ml) solution with 0.003mM NaHCO3.
Storage Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles.
Note For research use only.
Purity >98.0% as determined by: (a) Gel filtration analysis. (b) Analysis by SDS-PAGE.
Source Escherichia coli.
Activity Capable of inhibiting leptin-induced proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor. Its in vitro activity is 6-8 fold lower than the non-pegylated antagonist but in vivo it has profound weight gain effect (as compared to the non-pegylated antagonist), resulting mainly from increased food intake. Its in vivo activity compared to that of PEG-MLA is 9-27 fold higher.
Product Description

Recombinant of human Leptin tA protein

Solubility (25°C)
Solubility (25°C) It is recommended to reconstitute the lyophilized Leptin Antagonist Triple Mutant pegylated Human Recombinant 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.
