Obesity, which is characterized by excessive accumulation of adipose tissue in the body, has become one of the greatest public health challenges. Obesity is not only associated with health problems linked to increased weight-dependent pressure overload on lung, joints and bones, but also a important risk factor for life-threatening diseases such as cardiovascular diseases, type 2 diabetes and certain cancers.

Nesfatin is a naturally occurring hormone produced by brain cells. Japanese scientists discovered in 2006 that it is responsible for regulating appetite and producing body fat. Excess Nesfatin in the brain leads to a loss of appetite, less frequent hunger, a 'sense of fullness', and a drop in body fat and weight. A lack of Nesfatin in the brain leads to an increase of appetite, more frequent episodes of hunger, an increase of body fat and weight, and the inability to 'feel full.' This latter condition can be artificially induced by injecting an anti-Nesfatin antibody into the brain.

The receptors of Nesfatin within the brain are not completely understood, although they are thought to be contained in the hypothalamus and in the solitary nucleus, where Nesfatin is believed to produced via peroxisome proliferator-activated receptors (PPARs).

Protocol Outline
  1. Prepare all reagents, samples and standards as instructed.
  2. Add 100 µl detection antibody to each well.
  3. Incubate 1.5 h at RT or O/N at 4°C.
  4. Add 100 µl standard or sample to each well.
  5. Incubate 2.5 h at RT.
  6. Add 100 µl prepared streptavidin solution.
  7. Incubate 45 min at RT.
  8. Add 100 µl TMB One-Step Substrate Reagent to each well.
  9. Incubate 30 min at RT.

Standard, biotinylated peptide, and positive control should be stored at -20°C after arrival. Avoid multiple freeze-thaws. The remaining kit components may be stored at 4°C. Opened microplate wells and antibody (Item N) may be stored for up to 1 month at 2° to 8°C. Return unused wells to the pouch containing desiccant pack and reseal along entire edge.
