  • Relevance
    The cAMP-specific Phosphodiesterase type 4 (PDE4) family is comprised of 4 genes (PDE4 A, B, C and D) with multiple splice variants generated by RNA splicing and use of alternate initiation sites. The cAMP-dependent protein kinase A modulates the enzyme activity of some PDE4 family members by phosphorylation / dephosphorylation mechanisms. Such short-term regulatory mechanisms are necessary for rapid changes in the cAMP levels in cells. PDE4 family selective inhibitor, rolipram inhibits all members of the PDE4 family. In rodents inhibition of PDE4 enzymes by rolipram attenuated short- and long-term memory impairment produced by the administration of scopolamine and MK801. Interaction of these enzymes with cellular scaffolding proteins plays important role in PDE4 compartmentalization and cAMP-dependent signaling.

  • ab 14628 detecting 3 isoforms of PDE4A subclasses (PDE4A1, PDE4A5 and PDE4Ax) and two isoforms of PDE4D (PDE4D1, PDE4D3) in rat brain by Western blot.

  • ICC/IF image of ab14628 stained PC12 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 (ab14628, 1µg/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. This antibody will label most of the PDE4 proteins from PDE4A (PDE4A1,65 kDa; PDE4A5, 106 kDa, PDE4Ax 102 kDa);in PDE4B (generally it labels only PDE4B3 (100 kDa); PDE4D (PDE4D1, D2, D3, D4, D5) provided these proteins are e...
