Immunolocalization of α-lactalbumin in mammary glands. In glands with the lactating phenotype (A), α-lactalbumin was localized to cells in the lobular units (arrowheads) and the secretion within the ducts. The positive control lactating mammary gland showed similar staining (B), while the normal virgin mammary gland was negative (C). Scale bar: 50 μm
