Leptin Triple Antagonist Active Protein
Recombinant Ovine Leptin Triple Antagonist
Purity
Greater than 98.0% as determined by: (a) Gel filtration analysis. (b) Analysis by SDS-PAGE.
Synonyms
Leptin Triple Antagonist; Recombinant Ovine Leptin Triple Antagonist; Leptin tA Ovine; Leptin Antagonist Triple Mutant Ovine Recombinant; oLeptin tA; Leptin Triple Antagonist active protein
Host
E Coli
Purity/Purification
Greater than 98.0% as determined by: (a) Gel filtration analysis. (b) Analysis by SDS-PAGE.
Form/Format
The protein was lyophilized from a concentrated (0.65mg/ml) solution with 0.003mM NaHCO3.
White lyophilized (freeze-dried) powder.
White lyophilized (freeze-dried) powder.
Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Val-Pro-Ile-Arg
Solubility
It is recommended to reconstitute the lyophilized Leptin-Antagonist Triple Mutant Ovine Recombinant in sterile water or sterile 0.4% NaHCO3adjusted to pH 8, not less than 100 ug/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).
Biological Activity
MyBioSource's Leptin-Antagonist Triple Mutant Ovine Recombinant is capable of inhibiting leptin-induced proliferation of BAF/3 cells stably transfected with the long form of mouse leptin receptor. It also inhibits various leptin effects in several in vitro bioassays.
Preparation and Storage
Lyophilized Leptin Antagonist Triple Mutant Ovine Recombinant although stable at room temperature for several weeks, should be stored desiccated below -18 degree C. Upon reconstitution at > 0.1 Lep-tA mutant mg/ml and up to 2 mM and filter sterilization Leptin mutant can be stored at 4 degree 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.
