Description of Porcine Leptin

Leptin Porcine Recombinant produced in E. Coli is a single, non-glycosylated, polypeptide chain containing 146 amino acids and additional Ala at N-terminus, having a molecular mass of 16kDa.

Biological Activity

Biological active as evidenced by inducing proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor.

Reconstitution

It is recommended to reconstitute the lyophilized recombinant porcine leptin in sterile 0.4% NaHCO₃ adjusted to ph 8-9, not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Stability

Lyophilized Leptin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Leptin should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA, order number: 2835.955.xyz or 2835.958.xyz, or BSA, order number: 2835.919.xyz). Please avoid repeated freeze-thaw cycles.
