Effects of cardiopulmonary bypass on tight junction protein expressions in intestinal mucosa of rats

Figure 3 Western blot analysis of occludin and ZO-1 in terminal ileums. Lane 1: Control group; Lane 2: End of CPB; Lane 3: 2 h after CPB. A: Oclludin protein expression; B: ZO-1 protein expression. Total protein was extracted from rat terminal ileums. Band densities were normalized to the mean density of saline bands and expressed as % relative content. Gel staining was used as a loading control. Bars are mean % relative content ± SE, n = 10 for each group.
