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, LEP was mutated, resulting in L39A/D40A/F41A mutant. Leptin Antagonist Triple Mutant Mouse Recombinant was purified by proprietary chromatographic techniques.
The protein was lyophilized from a concentrated (0.65mg/ml) solution with 0.003mM NaHCO3.
It 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
Lyophilized 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 2 mM 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.
Amino Acid Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Val-Pro-Ile-GlnBiological ActivityNeoBiolab’s Leptin Antagonist Triple Mutant Mouse Recombinant is capable of inhibiting Leptin-induced proliferation of BAF/3 cel
Greater than 99.0% as determined by:(a) Gel filtration analysis.(b) Analysis by SDS-PAGE.
