Dual staining for E2 (green, A) and tryptase (red, B) of IH sections. a, b Multiple cells (white arrowheads) showed strong immunoreactivity for E2 (a) and tryptase (b) (IHC, × 200). c Cell nuclei were counterstained with DAPI (blue, C) (IHC, × 200). d Merged image showing multiple MCs (white arrowheads) dually stained for E2 and tryptase (IHC, × 200)
