E Coli
Recombinant Human Leptin (Anti-Obesity Protein) (rHuLeptin)
Greater than 95% by RP-HPLC, anion-exchange chromatography; reducing and non-reducing SDS-PAGE, silver stain.
Purification: Chromatographic
Sterile filtered, lyophilized.
<1% by SDSPAGE
Biological Activity
Fully biologically active compared to reference standards. ED50 determined by the leptin dependent stimulation of human OB-R transfected murine BaF3 cells is 0.5-1.6 ng/ml.
Endotoxin Level
<0.1 ng/ug
Protein Content
Determined spectrophotometrically at 280nm (extinction coefficient 0.878) and by RPHPLC analysis against a calibrated standard.
Soluble in water and most aqueous buffers above and below the isoelectric point. Dialyzed against 45mM sodium bicarbonate prior to lyophilization.
Preparation and Storage
Lyophilized product is stable at room temperature, but should be stored desiccated at -20 degree C. Upon reconstitution, store at 4 degree C. Avoid repeated freeze-thaw cycles.
Other Notes
Small volumes of lep recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
