Recombinant Human Leptin (LEP) | Z101859

abm | Recombinant Human Leptin (LEP) | Z101859

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.

Functions:

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