Fig. 2From: Detection of IKKε by immunohistochemistry in primary breast cancer: association with EGFR expression and absence of lymph node metastasisRepresentative photomicrographs of IKKε immunohistochemical staining of normal mammary gland and tumor breast tissues. Normal breast tissues (a and b) and breast cancer tissues (c–h) were stained with rabbit IKKε D20G4 antibody (a, c, e and g) or an isotype rabbit control (b, d, f and h). Specific IKKε staining was scored on a scale of 0–3. Representative images of intensities 0 (a), 1 (c), 2 (e) and 3 (g) are shown. Scale Bars: 100 μmBack to article page
