Description of Chicken Leptin
Leptin Chicken Recombinant produced in E. coli is a single, non-glycosylated, polypeptide chain containing 145 amino acids and having a molecular mass of 16 kDa.
Biological active as evidenced by inducing proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor. Its activity is however 5-10 fold lower as compared to mammalian leptins.
We recommend a quick spin followed by reconstitution in sterile water to a concentration of at least 100 µg/ml, which can then be further diluted to other aqueous solutions. Do not vortex.
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.
Amino Acid Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Val-Pro-Cys-Gln.
