Our Abpromise guarantee covers the use of ab3583 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ICC/IF Use a concentration of 5 µg/ml.
Inhibition Assay Use at an assay dependent concentration.
ICC 1/50 - 1/200.
IHC-Fr 1/50 - 1/200.
WB 1/200 - 1/1000. Detects a band of approximately 16 kDa (predicted molecular weight: 16 kDa).


Anti-Leptin antibody images

  • Immunohistochemical staining of Leptin in Sheep brain using ab3583.

  • Predicted band size : 16 kDa

    ab3583 at a dilution of 1 / 4000 staining leptin in mouse 3T3-L1 cell lysate by Western blot.

  • ICC/IF image of ab3583 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 (ab3583, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 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.

Thank you for your enquiry.

I can confirm that ab3583 and ab16227 antibodiesshould detect leptin both intra and extracellularlly.However based on the references for these product it appears that most if not all of the leptin is immediately s...

Thank you for passing some information to me.
I understand that ab3583 has been used previously at 1:4000.
Have you had a chance to test this antibody at dilutions of 1/500 or 1/1000 (for 1 hr at room temperature or overnight at 4oC?
