[Histonet] Ventana HER2 4B5

[Gagnon, Eric]

Hello Histonetters,
 
Anyone have any experience with Ventana HER2 4B5 antibody?  We are running the Ventana XT, and had some pathologist rumblings about c-erbB-2 (ASR)CB11, our previous antibody, giving some staining in non-neoplastic cells.  We are switching over to the 4B5, and wondering, can we expect better results?  Any feedback appreciated!
