Our Abpromise guarantee covers the use of ab3526 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
IHC-P Use at an assay dependent concentration. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
WB Use at an assay dependent concentration. Can be blocked with Perilipin A peptide (ab5009). By Western blot, this antibody detects an ~62 kDa protein representing Perilipin A from 3T3-L1 cell extract

ICC/IF Use at an assay dependent concentration. PubMed: 20335253


  • FunctionModulator of adipocyte lipid metabolism. Coats lipid storage droplets to protect them from breakdown by hormone-sensitive lipase (HSL). Its absence may result in leanness.
  • Tissue specificityAdipocytes.
  • Sequence similaritiesBelongs to the perilipin family.
  • Post-translational
    Major cAMP-dependent protein kinase-substrate in adipocytes, also dephosphorylated by PP1. When phosphorylated, may be maximally sensitive to HSL and when unphosphorylated, may play a role in the inhibition of lipolysis, by acting as a barrier in lipid droplet.
  • Cellular localizationLipid droplet. Lipid droplet surface-associated.

Anti-Perilipin A antibody images

  • Western blot detection of Perilipin A in 3T3-L1 cell extract using ab3526.

  • Immunofluorescence analysis of Human preadipocytes, staining Perilipin A with ab3526. An AlexaFluor®568-conjugated anti-rabbit IgG was used as the secondary antibody.
  • ab3526 (4µg/ml) staining perilipin in Human breast adipose using an automated system (DAKO Autostainer Plus). Using this protocol there is strong cytoplasmic staining of adipocytes.
    Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer citrate pH6.1 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min 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, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.

  • Immunohistochemical analysis of dog mammary adipose tissue, staining Perilipin A with ab3526.

    Tissue was fixed with formaldehyde and blocked with 1% blocking solution for 15 minutes at room temperature; antigen retrieval was by heat mediation in Tris-EDTA buffer (pH 9). Samples were incubated with primary antibody (1/200 in BSA in TBS) for 30 minutes. An undiluted HRP-conjugated goat anti-rabbit polyclonal IgG was used as the secondary antibody.

  • ab3526 staining Perilipin A in rat myofibers by Immunohistochemistry (PFA fixed).
    Freshly isolated single myofibers were collected in 0.5 ml DMEM, 5% HS in an Eppendorf tube. Fibers and satellite cells were fixed with 4% paraformaldehyde in phosphate buffered saline, rinsed in PBS and permeabilized with Triton X-100, 0.5% in PBS. After washing, fibers and/or cells were incubated with ab3526 at a 1/50 dilution overnight at 4°C or 1 hour at 37°C. Non specific interactions were blocked with 20% goat serum. They were then washed and incubated with labeled secondary antibodies for one hour at room temperature. Satellite cells were then mounted with fluorescent mounting medium plus DAPI 100 ng/ml. Fibers were collected and moved onto a polilysine microscope slide, and then mounted.
