Effect of zinc on the pro-apoptotic protein, BAX. a Western blot bands for BAX are shown for biopsy tissue from four zinc-treated patients (Z) and four placebo-treated patients (P), with cell lysates prepared and PAGE and immunoblots performed as described in Methods section, b densitometry of above bands expressed as mean ± SEM (P < 0.1, Student’s t test, one-tailed, n = 4). Densitometry that was conducted on a Memcode stain of total protein served as the loading control for each band (lane)
