  • Restrictions
    For Research Use only
  • Format
    Lyophilized
    Reconstitution
    It is not recommended to reconstitute to a concentration less than 100 μg/mL.
    Dissolve the lyophilized protein in ddH2O.
    Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
    Buffer
    Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4.
    Handling Advice
    Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
    Storage
    4 °C/-20 °C/-80 °C
    Storage Comment
    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.
    Expiry Date

    Background
    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.
