Description
Leptin Quadruple Mutant Human Recombinant is a single polypeptide chain containing 146 amino and additional Ala at N-terminus acids and having a Mw of 16 kDa, Human Leptin was mutated, resulting in L39A/D40A/F41A/I42A.Leptin Antagonist Quadruple Mutant was purified by proprietary chromatographic techniques.
Additional Information
Introduction NULL
Synonyms NULL
Source Escherichia coli.
Physical Appearance White lyophilized (freeze-dried) powder.
Formulation The protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3.
Solubility It is recommended to reconstitute the lyophilized Leptin Antagonist Quadruple Mutant in sterile 0.4% NaHCO3adjusted to pH 8-9, not less than 100
Stability Lyophilized Leptin Antagonist Quadruple Mutant 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.
