Table 2 b-galactosidase activity induced by PCB congeners (standard solutions)

From: Estrogen-like activity of seafood related to environmental chemical contaminants

Congeners Concentrations μg/mla b-galactosidase activity (percent of 10 nM E2)
PCB 28 5.0 31.10 ± 6.58
PCB 52 5.0 31.96 ± 7.82
PCB 101 5.0 18.35 ± 4.26
PCB 118 5.0 85.88 ± 19.79
PCB 138 0.05 20.95 ± 7.82
PCB 153 0.05 26.37 ± 5.63
PCB 180 5.0 22.92 ± 8.67
  1. aCongeners 138 and 153 were assayed at 0.05 μg/ml because at higher concentrations they strongly inhibited yeast cells growth
