Fig. 4. Western blot analysis of mouse atrial tissues.
For determination of the amount of Cav-1, Cav-3 and P2X7R, cell homogenates of atrium from wild-type and cav-1−/− mice were prepared and subjected to western blot analysis. 50 #g of protein from each sample was loaded on the gel. Western blot analysis was performed using rabbit anti-P2X7R antibody (dilution 1:500), rabbit anti-Cav-1 antibody (dilution 1:500), mouse anti-Cav-3 antibody (dilution 1:500) and anti-γ-tubulin antibody (1:1000). γ-tubulin served as a loading control. Representative data from 5 separate experiments are shown.
