Figure 4. Co-localization of φ575-cAMP with the type II regulatory subunit (RII) of PKA in adult ventricular cardiac myocytes.

Figure 4

Confocal images of myocytes expressing RII-ECFP (a,d) or loaded with φ575-cAMP (b,e) at low (left panels, scale bar 10 μm) and high (right panels, scale bar 1 μm) magnification. The merged images (c,f) demonstrate a high degree of co-localization between RII-ECFP and φ575-cAMP. This experiment represents an example of cells in which RII-ECFP exhibited a longitudinal striated pattern. PCC 0.41 ± 0.014, tM1 0.55 ± 0.014, tM2 0.71 ± 0.014, n = 9.
