Concordance in judgments among c‐erbB‐2 (HER2/neu) overexpression detected by two immunohistochemical tests and gene amplification detected by Southern blot hybridization in breast carcinoma

Abstract
We compared the c‐erbB‐2 protein overexpression status detected by the HercepTestTM (DAKO A/S, Grostrup, Denmark) with another conventional immunohistochemistry system using an anti‐c‐erbB‐2 rabbit p...
