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 ½+ or even 1+ in your lab?
Thank-you for your reply!
