PA1-052 detects leptin from human, mouse, and porcine samples.
PA1-052 has been successfully used in Western blot and ICC/IF procedures. By Western blot, this antibody detects an ~16 kDa protein representing leptin from human serum.
The PA1-052 immunogen is a synthetic peptide corresponding to residues S(91) R N V I Q I S N D L E N L R D(106) of human Leptin. This sequence is 94% conserved between human and bovine.
Leptin, the obese (ob) gene product, is a small protein expressed in and secreted from adipose tissue of normal rodents. Studies suggest leptin acts as a circulating hormone capable of regulating body-weight homeostasis and energy balance. One possible target tissue for leptin is the hypothalamus, a proposed control center for satiety and energy expenditure.
Ob knockout mice are characterized by several metabolic abnormalities including hyperglucocorticoidemia, hyperinsulinemia and insulin resistance, hyperglycemia, altered central nervous system activity, reduced metabolic rate of brown adipose tissue, and a large increase in white adipose tissue. Studies show that the administration of recombinant leptin to ob knockout mice reduces food intake and increases energy expenditure.
