IHC staining with ACIS analysis of Group 1 human placentas showing OD/nucleus values for smokers (, n = 7) and non-smokers (
, n = 7) using specific BPDE-DNA 27 antiserum, and absorbed BPDE-DNA antiserum (
). The graph also shows values for human keratinocytes exposed to 0.153-µM BPDE and stained simultaneously (with the placentas) using specific (
) or absorbed (
) BPDE-DNA antiserum.
