Localization of BGLAP in PDAC tissues by immunohistochemistry. Immunohistochemistry was performed using a specific BGLAP antibody as described in the Methods section. BGLAP exhibited a cytoplasmic and occasionally nuclear localization high-grade PanIN lesions (A & B) and cancer cells (C-E). The specificity of the staining was performed using control IgG (F). Insets show high magnification of structures indicated by arrows. A magnification scale bar of 100 μm is shown.
