Overexpression of α-B crystallin in infiltrating ductal carcinoma tissues of the breast. Formalin-fixed, paraffin-embedded sections were immunostained with rabbit polyclonal antibody against α-B crystallin. Tissues were stained with hematoxylin and viewed by light microscopy. A strong staining (brown) in tumor cells (T) has been observed, whereas α-B crystallin was expressed at lower levels in normal epithelial cells. (a) α-B crystallin expression in IDCA tissues (200x magnification), (b)-(c) α-B crystallin expression in IDCA (400x magnification), (d) α-B crystallin expression in nontumor tissues (400x magnification).
