Figure 6.

Anti-SK3, IK1 and caveolin-1 Western blot analysis of anti-caveolin-1 immunoprecipitates prepared from porcine coronary artery endothelium. Immunoprecipitation (IP) was performed with and without anti-caveolin-1 antibody (+ve and −ve, respectively). Supernatants remaining after IP (SUP) were also subjected to Western blot analysis. Note that the SK3 protein co-precipitates with the caveolin-1 protein, whereas the IK1 protein does not. Images are representative of five (SK3) and three (IK1) experiments.
