Leptine

Recombinant bovine leptin is an one polypeptide chain containing 146 amino and additional Ala at N-terminus acids and having a molecular mass of ~ 16 kDa. Bovine leptin was purified by proprietary chromatographic techniques, see Raver et al. Prot. Express. Purif. 19, 30-40 (2000) .

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

< 0.1 ng/µg of protein (< 1EU/µg)

> 98.0% as determined by Gel filtration and SDS-PAGE gel.

Recombinant bovine leptin is fully biologically active as evidenced by inducing proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor.
