Recombinant Human Leptin (LEP)

• Description:

  Leptin is a cytokine found in the adipose tissue of animals (Leptin mRNA is restricted to the adipose tissue). Leptin has been shown to suppress appetite, increase thermogenesis and reduce body weight, food consumption and plasma glucose levels.

• Gene Name:

  LEP

• Gene Aliases:

  OB, Obese protein, Obesity factor

• Gene ID:

  3952

• Accession Number:

  P41159

• Organism:

  Human

• Source:

  E. coli

• Concentration:

  <1.0 EU/μg of recombinant protein as determined by the LAL method

• Purity:

  >95% as determined by SDS-PAGE

• Solubility:

  Reconstitute at 1 mg/mL in sterile 20 mM Tris-­HCI (pH 8.0).

• Function:

  The ED(50) was determined by the dose-dependent proliferation of human umbilical vein endothelial cells and was found to be <0.5ng/mL.

• Molecular Weight:

  16.4

  Ambient Temperature

• Storage Conditions:

  The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.

• Appearance:

  Lyophilized Powder

• Formulation:

  Lyophilized from a 0.2 μm filtered solution in Tris-HCl and NaCl.
