[Histonet] Herceptest

From:"Orr, Rebecca"

Hello everyone,

Could you please let me know if you are using the Herceptest kit or the Herceptest antibody  and seeing any staining in the negative epithelials?

I would be interested in any response by anyone using a polyclonal antibody for Her2neu.

I understand this could be appropriate  staining and should be subtracted off the evaluation of intensity.



If you do see this, would you call it + or even 1+ in your lab?


Thank-you for your reply!
