Specificity
This antibody recognises rat leptin, a major adipose-derived hormone and member of the leptin family, which plays a key role in appetite control and the regulation of energy expenditure.Leptin is a recognized marker of obesity, which signals through binding to the obesity receptor (OB-R) in the hypothalamus. In humans there is a correlation between circulating levels of leptin and body fat mass, and defects in leptin production result in severe obesity. Regulators of leptin expression include insulin, cortisol, cAMP and thiazolidinediones.
