Leptin ELISA Kits

Leptin is an adipose-derived hormone that was discovered in studies of obesity in mice. It acts through a signaling pathway to regulate energy (food) intake and expenditure, maintaining homeostasis of adipose tissue. In humans, leptin is a 16 kDa protein, encoded by the LEP gene. Leptin is also known as obesity protein (OB), obesity factor, OBS, and LEPD. It is expressed mostly in white adipose tissue and acts through the leptin receptor, which exists as multiple isoforms. In addition to its role in adipose tissue, leptin regulates immune and inflammatory responses, hematopoiesis, angiogenesis, and wound healing. Mutations in the LEP gene cause severe to morbid obesity and hypogonadism, and are associated with the development of type 2 diabetes.

These kits are solid-phase sandwich ELISAs using two antibodies that are highly specific to leptin; one is precoated on the ELISA plate and the other is HRP-conjugated. These assay kits can be used to measure soluble human, mouse, or rat leptin protein in serum, EDTA plasma, or cell culture supernatants.
