Leptin functions via signaling pathways involving OB-R in hypothalamus. In mammals, leptin is mainly produced by the adipose tissue and encodes body fat reserves, acting as a short-term satiety signal. In fish, the presence of a leptin-like peptide was first evidenced by immuno-cross-reactivity, and its existence was certainly demonstrated after the finding by synteny of a leptin sequence in the pufferfish.\u003c\/p\u003e\n\n\u003cp\u003eSequence: Pro22-Cys171\u003c\/p\u003e\n\n\u003cp\u003ePurity: \u0026gt; 95 % as determined by reducing SDS-PAGE.\u003c\/p\u003e\n\n\u003cp\u003eFormulation: Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.\u003cbr\u003e\nNormally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.\u003cbr\u003e\nPlease refer to the specific buffer information in the printed manual.\u003c\/p\u003e\n\n\u003cp\u003eReconstitution: Please refer to the printed manual for detailed information.\u003c\/p\u003e\n\n\u003cp\u003eEndotoxin: \u0026lt; 1.0 EU per μg of the protein as determined by the LAL method.\u003c\/p\u003e\n\n\u003cp\u003eCalculated MW: 18.3 kDa\u003c\/p\u003e\n\n\u003cp\u003eObserved MW: 17 kDa\u003c\/p\u003e\n\n\u003cp\u003eStorage: Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80℃.
