Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 15 kDa (predicted molecular weight: 18 kDa).
ICC/IF Use a concentration of 5 µg/ml.
IHC-P Use a concentration of 5 µg/ml.


  • FunctionMay function as part of a signaling pathway that acts to regulate the size of the body fat depot. An increase in the level of LEP may act directly or indirectly on the CNS to inhibit food intake and/or regulate energy expenditure as part of a homeostatic mechanism to maintain constancy of the adipose mass.
  • Involvement in diseaseDefects in LEP may be a cause of obesity (OBESITY) [MIM:601665]. It is a condition characterized by an increase of body weight beyond the limitation of skeletal and physical requirements, as the result of excessive accumulation of body fat.
  • Sequence similaritiesBelongs to the leptin family.

Anti-Leptin antibody images

  • ICC/IF image of ab117751 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab117751 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

    Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/10000 dilution
    developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 18 kDa
    Observed band size : 15 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 34 kDa,49 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 8 minutes
    The band observed at 15 kDa could potentially be a cleaved form of Leptin due to the presence of a 21 amino acid signal peptide. This blot was produced using a 10% Bis-tris gel under the MES buffer system. The gel was run at 200V for 35 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 5% Bovine Serum Albumin before being incubated with ab117751 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution.
  • IHC image of Leptin staining in Human normal placenta formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab117751, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
