Appearance Lyophilized powder. Formulation Lyophilized after extensive dialysis against 50 mM Tris, pH 8.0. Endotoxin Level <0.2 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Rat Leptin (rRtLeptin) to 100 μg/mL using ddH2O. Storage & Stability Lyophilized recombinant Rat Leptin (rRtLeptin) is stored at -20°C. After reconstitution, it is stable at 4°C for 2 weeks or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping Room temperature in continental US; may vary elsewhere. Background A sensor (leptin production by adipose cells) monitors the size of the adipose tissue mass. Hypothalamic centers receive and integrate the intensity of the leptin signal through leptin receptors (LRb). Effector systems, including the sympathetic nervous system, control the two main determinants of energy balance-energy intake and energy expenditure[1]. Recessive mutations in the leptingene are associated with massive obesity in mice and humans, establishing a genetic basis for obesity. Leptin circulates in blood and acts on the brain to regulate food intake and energy expenditure. When fat mass falls, plasma leptin levels fall, stimulating appetite and suppressing energy expenditure until fat mass is restored. When fat mass increases, leptin levels increase, suppressing appetite until weight is lost. This system maintains homeostatic control of adipose tissue mass[2]. |
