Immunostaining of adhering cells (Figure 1B) showed a predominant cell membrane p185 expression; immunohistochemistry of paraffin-embedded HCPC I (Figure 1C, D) showed a medium-high p185 expression (2+) in almost all cells (as compared with breast carcinoma specimens, not shown, according to the manufacturer's instructions) (Dako Hercept Test, 2000). This evidence concerns the gene EIF3A and breast carcinoma.
