- Description
- PA1-051 detects leptin from human, mouse, sheep and rat samples. PA1-051 has been successfully used in Western blot, immunocytochemistry and immunohistochemistry experiments. By Western blot, this antibody detects an ~16 kDa protein representing leptin from 3T3-L1 cell extract. Immunohistochemical staining of leptin in sheep brain with PA1-051 results in staining of the ventromedial hypothalamus. The PA1-051 immunogen is a synthetic peptide corresponding to residues Q(25) K V Q D D T K T L I K T I V T R I N D(44) of mouse Leptin. This sequence is completely conserved between mouse and bovine.

- Immunofluorescence analysis of Leptin was performed using 70% confluent log phase 3T3-L1 cells differentiated with StemPro Adipogenesis Supplement (Product # A10070-01) for 5 days. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with Leptin Rabbit Polyclonal Antibody (Product # PA1-051) at 2µg/mL in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). F-actin (Panel c: red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing cytoplasmic localization. Panel e shows the undifferentiated cells that have lower level of Leptin expression. Panel f represents the no primary control. The images were captured at 60X magnification.

- Figure 5 Leptin protein level in pressure-overloaded hearts. Leptin protein level in the control rat hearts (control) and pressure-loaded rat hearts (banding) at 4 weeks after surgery. Leptin content in hearts was determined with Western blot analysis. GAPDH was measured as an internal control. n=2 in each group.
