Description of Ovine Leptin Triple Antagonist

Leptin Antagonist Triple Mutant Ovine 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, Leptin was mutated, resulting in L39A/D40A/F41A mutant.

Biological Activity

Leptin-induced proliferation of BAF/3 cells stably transfected with the long form of human Leptin receptor can be inhibited by recombinant ovine Leptin Antagonist Triple Mutant. It also inhibits various Leptin effects in several in vitro bioassays.

Reconstitution

It is recommended to reconstitute the lyophilized Leptin-Antagonist Triple Mutant Ovine Recombinant in sterile water or sterile 0.4% NaHCO₃ adjusted to pH 8, not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Stability

Lyophilized Leptin Antagonist Triple Mutant Ovine Recombinant although stable at room temperature for several weeks, should be stored desiccated below -18°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°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, order number: 2835.955.xyz or 2835.958.xyz, or BSA) is suggested. Please avoid repeated freeze-thaw cycles.
