| Biological Activity | Human Leptin is biologically active in the ob/ob mouse obesity model. The ob/ob mice were treated via intraperitoneal injection once daily at a dose of 5 µg Leptin/gm of body weight for 7 days. Significant effects on body weight, food consumption, and plasma glucose levels were observed to saline-treated controls. |
| Species Reactivity | Chicken, Monkey, Mouse, Rat, Human |
| Synonyms | LEP; OB; OBS |
| Description | Encoded by the ob (obese) gene, Leptin is an adipose-derived cytokine that suppresses appetite and increases thermogenesis. Leptin exerts its anorectic effect via signaling through a hypothalamic receptor termed OB-R. Leptin has been shown to reduce body weight, food consumption, and plasma glucose levels in various in vivo models. Recombinant human Leptin is a 16.0 kDa protein containing 147 amino acid residues. |
