Figure 5. Densitiometric scans of electrophoretograms of hepatic microsomes from rainbow trout pretreated with polychlorinated biphenyl congeners (A), control microsomes, 90 fig protein/gel (B), 2,2, 4,4 -tetrachlorobiphenyl-induced microsomes, 90 fig protein/gel (C), 3,3, 4,4 -tetrachlorobiphenyl-induced microsomes, 90 fig protein/gel (D), Aroclor 1242-induced microsomes, 90 fig protein/ gel. The slab gels were stained with Coomassie Blue-250 and individual sample tracts were cut out and scanned at 550 nm. The vertical broken line is at 57,000...
