Assay Protocol

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

Endotoxin

< 0.1 ng/µg of protein (< 1EU/µg)

Purity

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

Bioactivity

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