Application Notes
Immunocytochemistry: This IgG fraction has been found to stain specifically human adipocytes at a concentration of 10 ug/ml. The ability of this rabbit IgG to bind to leptin in adipocytes was examined in cells fixed with neutral buffered formalin. The fixed cells were incubated for 20 minutes with 4% goat serum. reacted for 60 minutes with the diluted rabbit antibody. and then with FITC-conjugated goat anti-rabbit IgG. The immunofluorescent staining pattern was observed using epifluorescence microscopy.
Western Blot: Western immunoblots of adipocyte homogenates result in a single band at ~ 16 kDa at a concentration of 20 ug/ml
Western Blot Protocol: 1. After SDS-PAGE (on either 4-15% gradient gels or single percentage gels. such at 12% gels) and electrophoretic transfer to PVDF membrane. block the membrane overnight with 4% normal goat serum using TBS/Tween-20 buffer.
2. Wash x 2 with TBS/Tween-20.
3. Apply the IgG fraction after dilution to at least 20 ug/ml (Note: higher dilutions may be needed). Use 2% normal goat serum in TBS/Tween-20 as buffer. Let the primary antibody bind for 2-4 hours.
4. Wash x 3 with TBS/Tween-20.
5. Apply affinity purified HRP-goat anti-rabbit IgG antiserum diluted 1:2500 (dilution may vary depending upon supplier) in 2% normal goat serum in TBS/Tween-20. Incubate 1-2 hours. Note: greater sensitivity may be achieved using ABC techniques.
6. Wash for 5 minutes x 4 in TBS/Tween-20.
7. Develop color using the enhanced DAB reaction.

Related Product Information for anti-Lep antibody
This IgG fraction was prepared by precipitation. dialysis and chromatography from an antiserum that was raised in a rabbit which was immunized with a peptide analogue of the amino terminal human of leptin(1-24) covalently attached onto a carrier protein. The antiserum has been shown to be specific for the amino terminal of leptin and has been characterized by western blotting. ELISA. and cell staining techniques. The IgG fraction is suitable for immunocytochemical and western immunoblotting detection of leptin. Dilute the lyophilized antibody with 0.1 ml of 10 mg/ml BSA in PBS for the equivalent concentration in whole antiserum. or with additional buffer for more dilute antibody. Each vial contains 2.03 mg of purified IgG.

NCBI Description
involved in regulation of body weight, and may have a role in angiogenesis [RGD]
Uniprot Description
Function: May 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.
Subcellular location: Secreted
Probable.
Sequence similarities: Belongs to the leptin family.

Researchers should empirically determine the suitability of the Lep lep for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Leptin IgG fraction, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
