Leptin antibody
Rabbit anti Human Leptin antibody recognizes human leptin, a ~16 KDa 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.

Product Details
- Target Species
- Human
- Product Form
- Purified IgG - lyophilised
- Reconstitution
- Reconstitute with 0.1ml distilled water
Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. Bio-Rad recommend that the vial is gently mixed after reconstitution. For long term storage the addition of 0.09% sodium azide is recommended. - 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.
- Buffer Solution
- Phosphate buffered saline
- Preservative Stabilisers
- None present
- Immunogen
- Recombinant human leptin (PHP198)
- Approx. Protein Concentrations
- IgG concentration 1.0mg/ml
Storage Information
- 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.

- 1This product requires antigen retrieval using heat treatment prior to staining of paraffin sections. Sodium citrate buffer pH 6.0 is recommended for this purpose.
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.
- ELISA
- This purified human leptin antibody may be used in an ELISA with recombinant human leptin (PHP198) as the standard.
- Western Blotting
- This purified human leptin antibody may be used in Western Blotting applications under either reducing or non-reducing conditions with recombinant human leptin (PHP198) as the positive control.
