Figure 1: Immunoreactiviy of 14F7 Mab in breast cancer. A and C:Hematoxylin and eosin staining of infiltrating lobular and ductal carcinomas,respectively. Observe: the very weak expression of NeuGcGM3 in theinfiltrating lobular carcinoma section (B) while an intense reaction with14F7 Mab was evidenced in infiltrating ductal carcinoma (D) (Brown color).Counterstaining with Mayer’s Hematoxylin (Blue color). White bar=100 µm.
