|---|---|
| Product 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. |
| Source | Escherichia coli. |
| Sequence Similarities | The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Val-Pro-Ile-Gln. |
| Storage Instructions | Lyophilized Leptin Antagonist Quadruple Mutant although 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 suggested. Please prevent freeze-thaw cycles. |
| Storage Buffer | The protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3. |
