靶标

  • 功能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.
  • 疾病相关Defects 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.

  • Immunocytochemistry/Immunofluorescent analysis of Leptin (green) showing staining in the secretion of NIH-3T3 cells. Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with ab16227 in 3% BSA-PBS at a dilution of 1:100 and incubated overnight at 4 �C in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjugated secondary antibody in PBS at room temperature in the dark. F-actin (red) was stained with a fluorescent red phalloidin and nuclei (blue) were stained with Hoechst or DAPI. Images were taken at a magnification of 100x.

  • Immunocytochemistry/Immunofluorescent analysis of Leptin (green) showing staining in the secretion of HepG2 cells. Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with ab16227 in 3% BSA-PBS at a dilution of 1:100 and incubated overnight at 4 �C in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjugated secondary antibody in PBS at room temperature in the dark.

  • Immunocytochemistry/Immunofluorescent analysis of Leptin (green) showing staining in the secretion of HeLa cells. Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with ab16227 in 3% BSA-PBS at a dilution of 1:100 and incubated overnight at 4 �C in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjugated secondary antibody in PBS at room temperature in the dark.

  • Ab16227 staining human placenta.
    Left panel: with primary antibody. Right panel: isotype control.
    Sections were stained using an automated system DAKO Autostainer Plus , at room temperature. Sections were rehydrated and antigen retrieved with the Dako 3-in-1 antigen retrieval buffer citrate pH 6.0 in a DAKO PT Link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 minutes. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 minutes and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.

  • Developed using the ECL technique

    Performed under reducing conditions.

    Exposure time : 3 minutes

Thank you for your reply.

The lab confirmed that leptin is cytoplasmic and not nuclear. The image as well as the legend shown on the product datasheet are therefore incorrect and I asked my colleagues responsible for the website to remove or u...

The antibody ab16227 is not conjugated to anything that will produce color. To use this for ELISA, you will need an anti-rabbit IgG antibody, conjugated to an enzyme that will catalyze a color-producing reaction. This enzyme is typically horseradish pe...

Thank you for your enquiry regarding ab16227 and your interest in our products. This antibody to Leptin has not been tested in Bovine. The sequence between human and bovine leptin only differ by 1 a.a. residue, so I would expect it to work, but we ...
