<br /> Immune complexes and aliquots of cell lysates (30 μg) were each resolved by SDS/PAGE and immunoblotted for PDE5 (1:5,000), PKG (1:5,000), IP3R1 (1:1,000), PDE3A (1:2,000), or PKAc (1:1,000). We were unable to secure an aliquot of an anti-IRAG antibody and could not directly test for association between IRAG and PDE5 in our studies. Although much less extensively studied, growing evidence also supports an important role for compartmentation of cGMP-based cellular signaling.

<br /> Of note, although the Cell Signaling and Atlas antibodies are from different companies, we are unable to confirm for sure that they react to different epitopes of PDE5, because Cell Signaling does not disclose the region of PDE5 that their antibody reacts to. However, the Atlas antibody works well for both western blot and immunohistochemistry (see below), whereas in our hands the Cell Signaling antibody works well for western blot, but does not work well with our immunohistochemistry protocol. Supernatant protein was quantified using BCA protein assay reagent (Pierce), and 20 mg of supernatant protein per sample was electrophoresed on NuPAGE 4-12% Bis-Tris gels (Invitrogen) and then transferred on nitrocellulose membrane using iblot (Invitrogen).
