Figure 1. Neonatal cardiomyocytes express CGB and InsP3R isoforms.

Figure 1

(a) Representative western blot shows that cardiomyocytes (CM) but not cardiac fibroblasts (CF) express CGB. PC-12 cells served as positive control, β-actin as loading control. (b) CM express all InsP3R isoforms; positive controls as indicated: CEREB - cerebellar microsomes, CHO - chinese hamster ovary cells, RIN - rat insulinoma cells.
