Determination of Her-2/neu oncogene amplification is important in the current treatment of breast carcinoma. In addition to fluorescence in situ hybridization (FISH) and immunohistochemical stain (HercepTest), chromogenic in situ hybridization (CISH) has been shown to be a sensitive and specific method to determine the Her-2/neu status of surgical specimens. The ...
