This antibody functions as an ELISA capture antibody when paired with Rabbit Anti-Mouse Leptin/OB Monoclonal Antibody (Catalog # MAB4981).

This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Mouse Leptin DuoSet ELISA Kit (Catalog # DY498-05) for convenient development of a sandwich ELISA or the Mouse/Rat Leptin Quantikine ELISA Kit (Catalog # MOB00B) for  a complete optimized ELISA.

3-25 µg/mL

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Scientific Data

Western Blot Detection of Mouse Leptin/OB antibody by Western Blot. View Larger

Detection of Mouse Leptin/OB by Western Blot. Western blot shows lysates of mouse ovary tissue. PVDF membrane was probed with 1 µg/mL of Rabbit Anti-Mouse Leptin/OB Monoclonal Antibody (Catalog # MAB498) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Leptin/OB at approximately 16 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Immunohistochemistry Leptin/OB antibody in Human Adipose Tissue by Immunohistochemistry (IHC-P). View Larger

Leptin/OB in Human Adipose Tissue. Leptin/OB was detected in immersion fixed paraffin-embedded sections of human adipose tissue using Rabbit Anti-Mouse Leptin/OB Monoclonal Antibody (Catalog # MAB498) at 3 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Rabbit IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC003). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in fat cells.

Mouse Leptin/OB ELISA Standard Curve. Recombinant Mouse Leptin/OB protein was serially diluted 2-fold and captured by Rabbit Anti-Mouse Leptin/OB Monoclonal Antibody (Catalog # MAB498) coated on a Clear Polystyrene Microplate (DY990). Rabbit Anti-Mouse Leptin/OB Monoclonal Antibody (MAB4981) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (DY998) followed by Substrate Solution (DY999) and stopping the enzymatic reaction with Stop Solution (DY994).

Background: Leptin/OB

Leptin is a protein product of the mouse obese gene. Mice with mutations in the obese gene that block the synthesis of Leptin have been found to be obese and diabetic and to have reduced activity, metabolism and body temperature. cDNA clones encoding Leptin have been isolated from human, simian, mouse, and rat cells. Mouse Leptin shares approximately 96% and 84% sequence identity with the rat and human protein, respectively. Mouse Leptin cDNA encodes a 167 amino acid residue protein with a 21 amino acid residue signal sequence that is cleaved to yield the 146 amino acid residue mature protein. The expression of Leptin mRNA has been shown to be restricted to adipose tissue.

A high-affinity receptor for Leptin (OB-R) with homology to gp130 and the G-CSF receptor has been cloned. OB-R mRNA has been shown to be expressed in the choroid plexus and in the hypothalamus. OB-R has also been identified as an isoform of B219, a sequence that is expressed in at least four isoforms in very primitive hematopoietic cell populations and in a variety of lymphohematopoietic cell lines (1-3). The possible roles of Leptin in body weight regulation, hematopoiesis and reproduction are being investigated.
