• 介绍：

  Leptin is a hormone secreted from white adipocytes and plays important role in the regulation of food intake and energy balance. Leptin functions via signaling pathways involving OB-R in hypothalamus. Animal models have revealed the influence of Leptin in reducing body weight and regulating blood glucose level. When mutations are introduced in obese gene, mice with impaired function of leptin are massively obese and in high risk of diabetes. Leptin deficiency reduces metablic rate. Leptin deficient mice are less active and with lower body temperature than normal animals. Human Leptin shares approximately 84% sequence identity with the mouse protein. Human Leptin consists of 167 amino acid residue including a 21 amino acid residue signal sequence and 146 amino acid residue mature protein sequence.

  Recombinant Mouse Leptin is produced by our E.coli expression system and the target gene encoding Val22-Cys167 is expressed.Lyophilized from a 0.2 μm filtered solution of 20mM PB, 300mM NaCl, pH7.5.

  Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.

  Reconstituted protein solution can be stored at 4-7°C for 2-7 days.

  Aliquots of reconstituted samples are stable at < -20°C for 3 months.

   

• 溶解性： It  is  not  recommended  to  reconstitute  to  a  concentration  less  than  100μg/ml.
  Dissolve  the  lyophilized  protein  in  distilled  water.
  Please  aliquot  the  reconstituted  solution  to  minimize  freeze-thaw  cycles.

• 储存条件： -20℃
