• Product nameAnti-PDE4D antibody
    See all PDE4D primary antibodies
  • Description
    Rabbit polyclonal to PDE4D
  • Specificityab14613 labels all PDE4D proteins including PDE4D1, PDE4D2, PDE4D3, PDE4D4, PDE4D5 variants. Does not cross react with PDE4A, PDE4B, PDE4D6, PDE4D7, PDE4D8, PDE4D9 or PDE4C. The antibody has not been tested against endogenous PDE4D, only recombinant proteins and we therefore cannot guarantee it will detect endogenous PDE4.
  • Tested applicationsSuitable for: WB, IP, ICC, ICC/IF, IHC-Pmore details
  • Species reactivity
    Reacts with: Mouse, Rat, Hamster, Human
  • Immunogen

    C-terminal cyclic peptide unique to all PDE4D subtypes variants.

  • Positive control
    • recombinant proteins (PDE4D1, PDE4D2, PDE4D3, PDE4D4, PDE4D5)



Our Abpromise guarantee covers the use of ab14613 in the following tested applications.

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

  • FunctionHydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes.
  • Tissue specificityWidespread; most abundant in skeletal muscle. Isoform 6 is detected in brain. Isoform 8 is detected in brain, placenta, lung and kidney. Isoform 7 is detected in heart and skeletal muscle.
  • PathwayPurine metabolism; 3',5'-cyclic AMP degradation; AMP from 3',5'-cyclic AMP: step 1/1.
  • Involvement in diseaseNote=Genetic variations in PDE4D might be associated with susceptibility to stroke. PubMed:17006457 states that association with stroke has to be considered with caution.
  • Sequence similaritiesBelongs to the cyclic nucleotide phosphodiesterase family. PDE4 subfamily.
  • Post-translational
    Isoform 3 and isoform 7 are activated by phosphorylation (in vitro), but not isoform 6. Isoform N3 and isoform 12 are phosphorylated on Ser-49, Ser-51, Ser-55 and Ser-59.
  • Cellular localizationCytoplasm. Membrane. Cytoplasm > cytoskeleton. Cytoplasm > cytoskeleton > centrosome. Found in the soluble fraction, associated with membranes, and associated with the cytoskeleton and the centrosome.

Anti-PDE4D antibody images

  • ab14613 (2µg/ml) staining PDE4D in human placenta using an automated system (DAKO Autostainer Plus). Using this protocol there is strong staining of the cytoplasm.
    Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer EDTA pH 9.0 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.
  • ICC/IF image of ab14613 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 (ab14613, 10µg/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.

  • Western blot using ab14613 and positive controls for PDE4D variants.
