Leptin (Ob, Obese Protein, Obesity Factor) (Biotin)
Description:
Leptin, a 16KD major adipose-derived hormone and member of the leptin family, which plays a key role in appetite control and the regulation of energy expenditure.
Secreted leptin associates with proteins within the bloodstream and is transported to the brain, where it inhibits or up-regulates the activity of neuropeptides such as neuropeptide Y (NPY) and alpha-melanocyte-stimulating hormone respectively. Leptin is a recognised marker of obesity, with 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.

Applications:
Suitable for use in ELISA and Western Blot. Other applications not tested.

Recommended Dilution:
ELISA: 0.25-1ug/ml
Western Blot: 0.1- 0.2ug/ml
Optimal dilutions to be determined by the researcher.

Storage and Stability:
Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute by adding sterile 40-50% glycerol, ddH2O. Aliquot and store at -20°C. Reconstituted product is stable for 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
