Immunohistochemical stainings of human prostate sections with isoform-specific EPAC antibodies. Peroxidase-based stainings were performed using an EPAC1 antibody in (A), or an EPAC2 antibody in (B). Immunoreactivity resulted in brown color. In control stainings, primary antibodies were replaced by phosphate-buffered saline (PBS). Shown are representative stainings from series with prostates from n= 5 patients in (A) and (B).
