Formulation:

Lyophilized from a sterile filtered concentrated (1 mg/ml) solution in 0.0045 mM NaHCO3.

Purity:

>95% by SDS-PAGE and HPLC analyses.

Biological Activity:

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