Anti-Leptin antibody produced in rabbit was used in western blotting of total protein extracted from intra-abdominal fat pad of mice.

Biochem/physiol Actions

Leptin is a hormone secreted by adipocytes and regulates energy homeostasis, inflammation and neuroendocrine processes, synaptic formation and memory condensation. The physiological effects of leptin are mediated by leptin receptors, ObR and LepR. Leptin is the key regulator of obesity and acts directly on neuronal networks to regulate feeding, metabolism, gastric mobility and energy homeostasis. The pathways that mediate the effect of leptin are JAK/STAT, PI3K and JNK.
