This product recognises human leptin, a 16KDa 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.

Where this product has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the product for use in their own system using appropriate negative/positive controls.
Western Blotting
This biotinylated human leptin antibody may be used in Western Blotting applications under either reducing or non-reducing conditions withrecombinant human leptin(PHP198) as the positive control.
Storage
Prior to reconstitution store at +4oC.
After reconstitution store at -20oC.
Storage in frost-free freezers is not recommended. This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use.
Shelf Life
12 months from date of reconstitution.
Antiserum Preparation
Antiserum to human leptin was raised by repeated immunisation of rabbits with highly purified antigen. Purified IgG was prepared from whole serum by affinity chromatography.
This biotinylated human leptin antibody may be used in a direct ELISA or as the detection reagent in a sandwich ELISA with apurified human leptin antibody(AHP1616) as the capture reagent andrecombinant human leptin(PHP198) as the standard.
