Kv7 channel protein expression in rat pulmonary arteries. Immunoblots of Kv7 channel α-subunit and α-tubulin proteins, using lysates isolated from whole rat lung or brain (A) or isolated rat pulmonary arteries (B). Each blot is typical of experiments repeated on tissues from at least 4 rats. Wells were injected with lysate containing 25 μg of protein. Numbers to the left of each blot indicate the positions of molecular weight markers (kDa). Each gel was cut to stain separately for α-tubulin (50 kD), used as a loading control.
